SiiLVERHey, i tried the Dxlevel 81
My FPS issues are gone, it's back to not go below 100
and my demo benchmark went from avarage 110 went to avarage 143 fps
I have more fps variability but that's ok i guess
and it seems that having MSAA and Mat picmip at max and all that thing made no difference (about 0.73 fps in the demo)
(i still sutter every 10 sec or so but the game is playable at least)
What is your OS? Do you have Game DVR turned off? What about window optimizations and game mode? HIgh performance power plan? What are your launch options?
I've found it very hard to debug this issue, as I don't get it on any of my PCs, on Windows or Linux, so any additional information is appreciated.
FreudShould interp always be an exact multiple of (1 / rate)? I remember reading (I think in Felik's config?) that 0.02 was a good value, which seems to contradict your and Comanglia's configs.
Also, is the tickrate in TF2 66 or 66.66...? (ie, is the minimum interp I should use 0.01515... or 0.015?) Again, I recall reading differing advice on this.
cl_interp should always be set to 0 (unless a community server is restricting cl_interp_ratio for whatever reason). Use cl_interp_ratio and cl_updaterate to control interp more precisely. (if cl_interp is set to 0, it will set to cl_interp_ratio / cl_updaterate). Your interp ratio should be set to the lowest packet interval where you don't have any packet drops. Most of the time this will be 1.
TF2's tickrate is 66. So, if you have cl_interp_ratio set to 1, and cl_updaterate set to the max of 66, you'll get a cl_interp of 0.01515151515.
