@Mulero do you have the latest AMD drivers installed?
Sorry no issue there, just thought log would provide you with what you need . So far so good. Thx
Radeon Software Version
@Mulero did you tried in windowed mode?
Yes, no improvement either. Same results. Tested in borderless again, same results.
@Mulero I think that you're CPU bound, that explains the sporadic drop in GPU load.
It takes 7ms for your CPU to submit all the commands to the GPU and more impressively it takes it 35ms to start a new frame. I will put some more CPU debugging tools in the next betas to investigate this.
After a few tests it seems that i am on paar with dx9 now (except for the shadow).
@gp20 can you clear your shader cache?
delete all the files in here : rFactor 2\UserData\Log\Shaders
that gets rid of the shadow issue
Thanks @4thworld. In DX9 I am not having any problems. Settings to max and 40 IA without any problem. About 45 FPS at first, then always above 60 FPS
Thanks for the quick hotfix 4thworld, Performance seems to be better than yesterday.
amd r9 380 4gb (asus strixx) This could be a problem,i'm stuck on driver 16.11.5 because of incompatibility with this board and the new amd voltage manager called wattman,that cause black screen and no control over fan and voltage)
windows 10 x64 creator update
This is My result:
PerfLog_2017-5-4-18-18-13- in cockpit view
PerfLog_2017-5-4-18-19-41- external view
one thig that i noted is the front wing of the usf2000, it have some missing parts.
external view displayed more fps than cockpit view
I let the ai to drive the car, dont know if this can affect the result
this is my setting:
Now all maxed with AA5 and PP ultra i get 85 fps avg.
Here is the log.
What about the amd virtual super resolution?
Much lower frame rates than from DX9. Less Hitching but still present.
Win 10, AMD 8320 @ 4.0 GHz, 16GB Ram, R9290 4GB. Latest Beta build. AAx2, No PP. NOLA w/ GT500
Same but with AAx5 and track detail set to High.
These performance variations have happened to me too.
With any graphical configuration change that I make, the performance is a little worse. I have to clean cbash and shaders to go back to the proper adequate performance, so maybe there are some dirty bits here and there in some of those files that get even dirtier with every change.
It has disapear with the right branch.
@4thworld @Mulero I tried both DX9 and DX11 and yes, on DX11 one thread is constantly at 100% (even without PP). On DX9 it's quite high, but usually stays below 100%. DX9: ~100fps, DX11: ~60fps no PP, USF @ silverstone international with 15 AI cars.
@4thworld @Proscribo I can confirm that in DX11 only one nucleus is working between 80% and 95%. Rest of nucleus are doing nothing.
I will close this thread because after the patch some people had their issue fixed.
I will open a new one with the difference in frame rate between DX9 and DX11.
yes i think i know what's happening in the next build i will try to modify one thing for users like you, i'll keep you updated.
