Full screen with multiview is not working with latest Build ID : 1905199. rFactor 2 is running in windowed mode when full screen is selected. There is also problem with GPU load when VIDEO Sync is used. Max GPU load is 90% with VIDEO sync on, sync off it is 100%. Third party content is much worse. Max GPU load is 70% with VIDEO sync on. I have done clean install of latest Nvidia driver 382.53 with DDU. Uninstalled rFactor 2 and deleted all user files and installed rFactor 2. Latest build has also worse performance and rF2 is unplayable like it is now.
Ari, I think there may be another build out, I just fired up steam and there rF2 stuff waiting for me...my version now says 1905835
I did just copy and paste build ID from the forum: https://forum.studio-397.com/index.php?threads/official-dx11-beta-updates.55357/page-2#post-900645 My version says also 1905835. Thought that forum is up to date.
New bug. Triple screens > multiview > 5760x1080@120 HZ/FPS. When IGPU is used with 60 hz monitor rFactor 2 is running at 60 fps. There are loads off rapports about full screen triples etc. I think it is huge time to S397 devs take VR headsets off and do few laps with triple screens. I am losing my faith to you guys.
I to have had a decrease in performance since the last build with triples. Have gone from full settings down to high.
Wouldn't that make some sense, with vsync less GPU consumption? You say with third party content much worse - I don't understand and less GPU "with vsync" makes sense - unless I'm missing the boat For me, full screen seems to be working as expected - 5780x1080, fullscreen, with Multi-View, ALT-TAB working. Without vsync my GPU is at 100% (90-110 FPS, US2000 on Toban), with vsync 60% or so (of course 60 FPS, same combo). If I leave Windows at 60Hz (5790x1080) but set rF2 at 50Hz, with vsync, I get 50FPS with GPU roughly at 50% - makes sense. If I change Windows resolution to 50Hz but rF2 still at 60Hz "with vsync" I get 60FPS, not the Windows refresh rate - makes sense. My $.02
Video sync on with 120hz monitor you should get 120 fps all the time and GPU load should increase when fps drops below 120 fps. ISI/S397 content Video sync on GPU load increases to max 90% when fps drops but it should increase to 99-100%. Your windows resolution should have nothing to say when you are playing rFactor 2 in full screen mode and if it does and you are using full screen mode your rFactor 2 is running in windowed mode.
I only run a single screen and use vsync in game at 60 fps and the green GPU bar is always at 100%. Should it not be?
I agree, Windows refresh rate should not have anything to do with the rF2 refresh rate if in fullscreen - that's my point, fullscreen is running fine for me. Regarding GPU load, if the GPU is capable of producing a framerate higher than the monitor's sync, the load should "decrease" if you cap the framerate. If uncapped (no vsync) my GPU will run full speed (110 FPS in test), but with vsync it doesn't have to work as hard hence the decrease in load (60 FPS with sync). If the GPU can't maintain 60FPS (60Hz vsync), then yes the load should increase during this time. I did another simple test (same track/car combo), but this time I increased the graphical settings so I couldn't maintain 60FPS. In this case the GPU load increased to 100% as expected. Again, maybe I don't see the point you are trying to make but for me fullscreen with sync/no sync and GPU load correlate. Or else my hardware/software is not affected by what's causing your issue. i7 3770, GTX 1070, 16 GB, latest NVidia drivers, Windows 10 Pro. EDIT: I re-read your message - I think you are questioning why your GPU is only at 90% when the frames drop below 120. I agree, if it can't maintain 120 then the load should be at 100% (mine does max out at 100%). As for full-screen, I'm not sure why you're not seeing full-screen functionality - seems fine here.
The strange thing is that GPU load is 100% when sync is not used. I believe that fullscreen is running in windowed mode and it is OS sync buffer which is causing low GPU load and bad game experience. I thought first that it is only multiview related but if you read this thread it is not: https://forum.studio-397.com/index.php?threads/dx11-beta-no-full-screen-at-res-1920-x-1080.56400/
This is where you throw me Ari, you say "..GPU load is 100% when sync is "not" used." It would be normal for the GPU to be 100% "without" vsync , it's going to give you the highest framerate possible, if the GPU isn't bottlenecked by the CPU.
I obviously mean in my post #10 "The strange thing is that GPU load is 100% when sync is not used" that GPU load should also be 100% with Video sync when fps drops below 60/120/144 fps when 100% GPU load is needed and not 90% with ISI/S397 or 70% with 3p content. I don`t think GTX 1080 Ti SEA HAWK EK X is bottlenecked by the i7-5960X.
