tried both multi-player and single(issue same. Same laps/time ish aswell) with ai no ai lots ai turned off replays told bios to not throttle cpu if hot (cleaned case out aswell) updated nvida drivers and t500 wheel drivers tried all assorted gfx options fresh rf2 install no mods just 397 gt3 packs etc next is fresh install (hope to avoid) issue is after doing 1 lap or so i fps tanks from 60(vid card vsync) to less than 20 sometimes single digits. its also happening exactly the same in automobalista but no other games using the wheel or any other game that dosnt whenever i return to pits fps goes back to normal and i can leave the pits again full fps till ive done 1 or 2 laps any idea would be appreciated EDIT: tried fullscreen and borderless problem is exactly the same either way also all como's of game vsync and video driver vsync thou when ever i get the fps drop if i hit the windows key (works fullscreen and borderless) bring up the taskbar then click back to game fps is fixed Operating System: Windows 10 Home 64-bit (10.0, Build 17134) (17134.rs4_release.180410-1804) Language: English (Regional Setting: English) System Manufacturer: System manufacturer System Model: System Product Name BIOS: BIOS Date: 01/28/16 21:31:20 Ver: 05.0000B (type: BIOS) Processor: Intel(R) Core(TM) i7-6700 CPU @ 3.40GHz (8 CPUs), ~3.4GHz Memory: 16384MB RAM Available OS Memory: 16300MB RAM Page File: 7861MB used, 14837MB available Windows Dir: C:\WINDOWS DirectX Version: DirectX 12 DX Setup Parameters: Not found User DPI Setting: 96 DPI (100 percent) System DPI Setting: 96 DPI (100 percent) DWM DPI Scaling: Disabled Miracast: Available, with HDCP Microsoft Graphics Hybrid: Not Supported DxDiag Version: 10.00.17134.0001 64bit Unicode Card name: NVIDIA GeForce GTX 1070 Manufacturer: NVIDIA Chip type: GeForce GTX 1070
Ok first things first: 1) Are your graphics drivers up to date? 2) Are there and programs running in the background that you could turn off? 3) Are you Windows System & Drivers all up to date?
Also make sure you're not running any "beta" Build of any kind, right click Rfactor2 in Steam (select Properties) and on the Betas Tab select "Opt-Out of all betas"
1:yes did it all today 2: yes did all i could (also had task manager up while playing to see usage when drop hit ram 30+% didnt take note of cpu % thou it was low too) 3: yes i think so i always let it update its self and yes im opt'd out of all beta's it really seems as if the game goes into background mode when fps drops hit . esp seems so w/e i press windows key or alt tab the fps is fixed thou no other game on my system dose this onli rf2 and automobalista and this is new behavior since just before xmas it was fine
absolute lowest settings . same result 7 mins in fps loss same time as was for my default gfx settings med to high
Definitely sounds like loss of focus. There are programs you can use to try and work out which program is stealing focus, google has brought some up but I don't want to recommend any because I don't know them well - I feel like there was a discussion about this here maybe. @JimmyT mentioned one fairly recently, maybe he can advise?
The Windows power management sounds like a posible culprit. As you heat up the cpu, it lowers the temp by decreasing the power. Set your power settings to performance, see if that helps.
Windows Focus Logger is the program from Adminscope. Use this at your own discretion as it logs windows activity. I haven't noticed any unauthorised outbound transmissions but I'm not a security specialist. Also, I'm just some bloke you don't know so don't trust me, do some research first, I did. The focus logger found that a background program (can't remember which now, might have been anti virus????) was stealing focus and if it took it long enough the game would crash while waiting for graphics to come back.
Just found the other thread and this also helped me at the time. Thanks @MarcG for the tips back then. https://forum.studio-397.com/index.php?threads/steam-vr-steals-focus.60969/#post-957351 The pause on loss of focus tweak was most helpful. From MarcG - In your player.json search for the following and change 'true' to 'false', it might not help but may be worth a try: "Pause If Focus Lost":true, "Pause If Focus Lost#":"whether to automatically pause if window loses focus (single-player only)", Oh and it was steam VR that was stealing the focus in my case.
I'm pretty sure that Windows doesn't directly decrease CPU power, at least not for games or programs you run in foreground. Lowering CPU power would screw up gaming completely because temps are expected to rise while stressing the CPU. CPU's already have inbuilt logic to throttle down when temperatures get very hot.
Thank you ALL for the replies. tried pause if focus lost / same result also looked into and used focus logger. just rf2 showing then explorer 5 mins after thou im sure this is me tabbing to see the focus logger no other programs showing up im doing all the same test now 30 cars @ sebring and its always (2hr practice) fps drop is @ 115min to go mark there abouts i played 7 days to die last night after trying to fix this spent 4 hrs in game no issue. its just rfactor and automobalista, its got me buggered
Do you have programs that consume RAM or GPU RAM running in background? Because when rF2 gets starved out of VRAM or RAM, it starts to behave similarly for me. In Windows 10 task manager performance tab (you can leave it running in background) you can track both RAM and GPU RAM usage (under the new GPU tab).
no programs that dont have to be are running. been through task manager cpu is @ 50% system ram 30% GPU 3d is at 100% and ram usage is 50%. w/e the drops hit gpu goes to 25% ish and exactly same usage as if i just tabbed out in fact fps is same when i do intently tab out. so i think for some reason somthing is forcing it to go into that mode.
ok so last resort was taken windows 10 cd was dusted off and applied let game run 10 mins in car no slowdown issue seems resolved still no idea what caused it but obv it was in my system. ty all for the replies and help
There is a program called "allways on top" (just google it) that lets you set what ever window to stay on top. not entirely sure if i will solve this problem, but you who have this problem might want to give it a try? It works so that you select the window that you want to stay on top simply by clicking it, and then use the hotkey (ctrl space) to lock it on top.
