ATTENTION!
Stutters on ATI + CF and SLI users - we need your help!

+++++++++++++++++++

Set all driver settings to default.
Set all graphics settings to following ones (it may depends on your monitor resolution, so if you have different monitor resolution - do two tests - one with 1600x1200, another with your native resolution, but if you cant use 1600x1200 - just do the native one, dont forget to note resolution and memory usage during test).

If its possible - install any kind of monitoring tool, id reccomend you this one -

MSI Afterburner

Turn OSD display functions on - so youll be able to see your GPU usage level and FPS.

Test conditions:

TEST 1

Attached File  ROF_ATI_5870_TEST.jpg   255.91KB   3704 downloads

Attached File  QM_Settings.jpg   725.21KB   3703 downloads

Check for the stutters - if it present or not.

TEST 2

Turn Super Sampling on, set AA on 2x - and repeat test.

Dont forget to Note your PC configuration and drivers version.

My test rig is following:

CPU: i7 930 @ 3.88Ghz
RAM: 12Gb
GPU: ATI 5870 1gb

Drivers: cat 11.7

Results:

TEST 1

- video memory usage - 82% ;
- fps are ~65, when you low over ground, GPU usage ~70% ;
- fps are ~70, when you over than 500m, GPU usage ~60% ;
- no stutters at all;

TEST 2

- video memory usage - 91% ;
- fps ~45 - when you low over ground, notable stutters, in this case GPU is overloaded - it runs on 99%, supersampling does its job good on load GPU to its limits;
- fps ~65 when you climb over 500 meters, very rare stutters - GPU load is 95-97%

PS: actually i have 2x5870 on my rig - and when im running em in CF mode - no stutters with SS on, as GPU`s can hold it.

Thanks!

69% video usage memory
fps 19-22 down low
21-25 up high
few stutters (stunningly!)

Test 2: 74% graphic memory usage
fps 10 down low, same up high
it was jerky through out

Test 1:
69% Video memory usage
FPS unknown, but significant stuttering from sea level to at least 3000m (game is just barely playable). Altitude seems to have no effect at all on the severity of stuttering.

Test 2:
74% Video memory usage
Stuttering is even worse, rendering the game completely unplayable.

CPU: Q6600@2.8Ghz
RAM: 4Gb
GPU: ATI 5850 1gb
Win7 x64
Drivers: cat 11.8 - 1920x1080

Results:

TEST 1

- video memory usage - 82% ;
- fps are ~31 (parked), ~25 when you low over ground, notable stutters, GPU usage ~99% ;
- fps are ~36, when you over than 500m, GPU usage ~70% ;
- stutters until 500m, no noticeable stutters when flying at 1K;

TEST 2

- video memory usage - 91% ;
- fps ~25 parked, ~23 when low over ground, notable stutters, GPU always 99%;
- fps ~36 over 500m, some stutters - GPU load is 97-99% (if looking for tail, with cities and brown war zone behind the plane, fps can go to ~19).

EDIT: using trackir5 (don't know if this matters, guess not, but just in case)

My test rig is following:

CPU: Phenom II X6 1055T
RAM: 4Gb
GPU: ATI 6850 1gb
Win 7 64 bit
Drivers: cat 11.6
Resolution 1680x1050
Mods in RoF: off

Results via MSI Afterburner:

TEST 1

- video memory usage - 82% ;
- fps 28-40, when low over ground, GPU usage initially 99%, averages in the low 50% ;
- fps 40-53, when over 500m, GPU usage between 40 and 50%, averages in the low 40% ;
- no stutters at all;

TEST 2

- video memory usage - 91% ;
- fps during the whole test under 10, mostly around 6, extremely sluggish and notable stutters when low over ground, still below 10 fps after climbing despite it feels not quite as extreme as when flying lower, GPU usage initially 99% then between 57-92%;

Strange results. Very surprised here to see GPU usage does not getting maxed.



Out of curiosity I did a third test with Super-sampling on and landscape reduced from high to med.

alternative TEST

- video memory usage - 52% ;
- fps 27-34, when low over ground, GPU usage initially 99%, always above 78%, averages in the low 80% ;
- one short initial hang, afterwards no stutters at all;

So basically you have to either turn Super-sampling off or reduce landscape quality to med, the second one leading to better GPU usage at least on my system.

System details:

CPU: Intel i7 2600K @ 4.5GHz
RAM: 16Gb DDR3 1866
GPU: AMD HD6970 2GB
Win 7 64 bit
Drivers: Cat 11.8
Native Resolution 2560x1600

MSI Afterburner results:

TEST 1 (1600x1200)

Below 500m, FPS 82-90, VGA memory usage - 94%
Over 500m, FPS 82-95, VGA memory usage 75- 85%
No stutters at all during test using mouse look, slight stutters using TrackIR 5

TEST 2 (1600x1200)

Below 500m, FPS 42-53, VGA memory usage - 99%, bad stutters
Over 500m, FPS 66-75, VGA memory usage 75- 85%, stutters reduced but still quite bad


TEST 1 (2560x1600)

Below 500m, FPS 75-85, VGA memory usage - 92-97%
Over 500m, FPS 75-85, VGA memory usage 92-98%
No stutters at all during test using mouse look, slight stutters using TrackIR 5

TEST 2 (2560x1600)

Below 500m, FPS 18-35, VGA memory usage - 99%, very bad stutters
Over 500m, FPS 31-45, VGA memory usage 99%, bad stutters

It seems that as long as the GPU usage doesn't go near 100% stutters are kept to a minimum. I have had to reduce my graphics settings to get the same stutter free performance I was getting pre 1.021.

Because you have a fairly crappy videocard that simply cant cope with these settings.

And that's why set my grpahics setting lower than these two tests .. I normally have a lower graphics settings than bioth of the test cases .. But the thing is that i've seen a degradation of performance using my tried and tested graphics settings .. So by changing nothing on my side – the sim performance is lower ..

The Radeon 5450 is indeed rather low-end these days. However you use a low-ish resolution and with using not too demanding settings you still can enjoy many games with it including RoF.

For comparison sake, you can use the TH benchmark list for common graphic cards in 2010:

http://www.tomshardw...lized,2486.html" onclick="window.open(this.href);return false;">http://www.tomshardw...com/charts/2010 … ,2486.html

The weakest card listed, the Radeon 5550, which ist still marginally more powerful than the 5450, has in this test between 8 and 9% of the performance of the strongest setup, a 5870 Crossfire.

I have same card which seemed quit capable last week.
I bought my computer to play this game and it seems to me if the card was adaquate when I bought my ROF CD from the computer store I should still be able to play it for the life of the computer.

I am a sims novice. This my first computer game and Ive gone through alot of growing pains just to get to enjoy the game and now its been taken away

All I want is a a fix so I can fly again, not someone telling me now my cards to crappy to play. that aint right and you aint skinny

First of all, I didnt say you cant play the game with that card. But surely you cant play it at the very high settings suggested in this thread; You wondered why your videocard was at 99% utilization rate, and I told you why, its a very lowend card, sorry to tell you. You need a very decent gaming card to be able to run RoF with those settings. With your videocard, obviously the videocard will run at 99% and still lag terribly at those high settings, you will need to set gfx settings low to have a chance of reasonably smooth play.

BTW, whomever sold you a 5450 for playing RoF should give you a refund. Its really not a gaming card. For just a tiny a little more money you could have gotten something 3-4x as fast.

Lastly, and OT, but your cpu is dual core. There are known issues with dual core CPUs and windows 7. 1.021 supposedly fixes that, but in case it doesnt, it might still be worth trying this previous fix:

Thanks for the Core 2 Duo Tweak .. My frustration comes from the fact that the card I have worked perfectly, with my settings, on every update until this one. I'm being constructive and helpful by doing tests at settings beyond what i normally use… I hope this helps … My only fear is that I get another card and with a short period, more updates will happen and make that redundant.. This happened in IL2 and Cliffs of Dover is pitched so high a spec that only the dedicated (or rich) can play it. I'm hopeing that there is a fix in the making and that it gets done soon …

First of all, he doesnt have 4GB of videoram. Probably 1GB.
Secondly, the quoted figure in CCC, as I understand it, is the load on the shaders, it has nothing to do with the texture load (vram used) you see in the configuration app. The shader load gives you an idea how "busy" the videocard is, more or less comparable to CPU load you see in taskmanager for your cpu.

Posted 02 September 2011 - 15:37

Actually, no. A 4650 is (considerably) faster than 5450.
Moreover, the number is not a measure of performance. If anything, its closer to the opposite, as a weak GPU would be "busier" than a fast one. Also, dont read too much in to that number. A videocard is much more than shaders (there also ROPs, vram memory bandwidth and other potential bottlenecks).
Lastly, a faster or slower CPU could change everything as well. If the CPU cant keep up, the GPU may not be fed data fast enough, resulting in a low usage %.

Yep. Higher numbers dont mean faster cards. With AMDs numbering, the first digit indicates the generation so a 5xxx card is newer than a 4xxx, but it says nothing about performance. The second number is far more indicative of performance; the lower it is, the lower its performance within that generation, a x4xx card is bottom end, a x6xx is usually lowend/mainstream.

Anyway, look up any benchmarks, its not like a 4650 is anything like fast, but lets say a 5450 iseven slower. Note the top end card in that review, the 4770, is by any measure today, a rather slow card. A 5450 really is not a gaming card, its a good card for hometheatre PCs, playing movies, anything really, other than.. 3D gaming. Fortunately though… ->

Also, I noted that he has a dual core cpu and I have a quad core so there is that.

Of course there is more to it than the number of cores, but RoF is indeed quite CPU heavy. I was rather shocked when I did some benchmarking and found underclocking my videocard (5850) by more than 50% essentially made no difference once airborne. Thats with a 3.2 GHz quad core, relatively high gfx settings, and yet Im almost completely CPU limited:

My system specs:

ATI 4890 1GB @900/1100MHz
Resolution 2048x1152
6GB RAM
RoF on SSD
Other details in my profile
Oh, driver version is 10.5 :oops: (nope, no typo there :roll: )

Attached some screenshot from RivaTuner (v2.24, used for UC' (desktop), OC' and fan profiling) with frame rate and GPU load profile (only at above resolution).
Basically started on the ground, then flew a bit over ground and then climbed to 1km (with time compression => small ditch around the middle); always maneuvering and panning the look around.

Lower settings (81% memory):
Max. GPU load. At start about 40-50 FPS on the ground and almost always 60 or above once in the air. No stutters in flight maneuvers, if at all then very few while heavily panning the view around.
Attached File  rof_test1low.GIF   36.34KB   563 downloads

High settings (91 % memory):
Max. GPU load. ~20-30 FPS at start and 30-35 once started, going up by another 5-10 FPS at 1km. Serious stutters while panning around and also in any flight maneuvers, with little or no effect of the higher altitude => unplayable.
Attached File  rof_test2high.GIF   40.73KB   563 downloads

Below my personal settings and the results with those (96% Memory):
Limited to 60 FPS, some post processing, second highest settings for reflections, wood viewdistance and shader quality, but max. light sources and shadows "special:high" (might be that the last was set like that also for the other runs…)
Attached File  RoF_Settings.GIF   101.75KB   563 downloads
The results show the GPU "at the edge", near max. load, but the frame rate also at 60 FPS for most of the time. No or hardly any notable stutter.

TEST 1

- video memory usage - 82% ;
- fps are ~15-20, when on ground, GPU usage ~99-100%;
- fps are ~30-50, when over 500m, GPU usage ~99-100%;
- bad stuttering on ground, lessens significantly when wheels leave ground. Stuttering lessens as you get higher but is still there;

TEST 2

- video memory usage - 91% ;
- fps ~ 4-5 when on ground, GPU 99-100%, frame rate so bad impossible to note stutters;
- fps ~18-25 when over 500 meters, GPU 99-100%, stutters still present.

GPU load stuck on 99-100% in all situations in game and is at 40% on QMB screen and 0-16% on loading screen if this helps.

Looking forward to maybe some sort of hotfix. The game ran very well prior to this patch!

Many Thanks.

Please Ignore my earlier post below; 1.21 runs fine all maximum settings at stock clocks and voltage on graphics card. Not sure if was coincidence or whether 1.21 stressed system more than usual but have not had to change over-clock for some months. No stuttering encountered.

Cannot run game to test settings since 1.21 Have tried clean install etc. Prob seems to be with RoF only. (Dxdiag; no problems. Other sims no (new) problems. 5970 BE 2048. i7 at 3.2. win 64. drivers 11.8. Have tried fps limit, low settings etc.

Will look for earlier version of game or await hotfix/patch?

i5 760 2,67 oc to 3GHz
ATI 5850 1GB cat. 11.7
4GB RAM DDR3 1600
Win7 64bit

Test1

FPS on ground 48-52
FPS on 1000 meters 58-61
No strutters at all, GPU usage 86-88%

Test2
FPS on ground 28-32, slight strutters, especially when looking on ground
after take off - FPS on 40, fluent
on 1000m - FPS at 50, when looking backward 36-38 and strutters (because i am looking at the exhaust smoke)
GPU usage 100%

Request #1 - I want someone who has bad stutters to simply re-install the entire game to see if it changes anything. Just install into a different directory and copy over any important files like input.maps etc.

Re-install ALL of the M$ libraries including Direct X.

Request #2 - Can someone who had stutters and has a handy cam please film their screen as you fly, put on Autopilot or something and try to capture these "stutters" you are seeing with the horrible FPS. I need to see what you are seeing. Try to film in HD and put on YouTube. I need some frame of reference.

Something is real screwy if some are having bad stutters and some are not.

Lucas-1Esk - Can you post your ATI Catalyst Settings?

Jason, some people are running these tests on relatively lowend hardware. I wouldnt expect something like a 4770 or similar to be able to run everything high/maximum without stutters, these cards simply dont have the shader performance to pull that off (and therefore getting 99% GPU load).

Some of these settings also put a very high load on the CPU, like the maximum forest visibility and maximum reflection settings, which I have found to make a dramatic impact on performance even when the GPU is barely loaded (see here Gfx settings and performance guide (W.I.P)), so I assume they are putting a huge strain on the CPU.

Im not saying there isnt an issue here, but Im not sure what these results will tell you, unless you get them from someone with top notch hardware that ought to be able to run those settings.
