— My specs:
12700k, 3080, 32g RAM, Evo M.2 SSDs, 1440@165Hz, FS2020 at Ultra Settings (CPU/GPU at stock speeds).
— My Question:
Should I expect more FPS using DLSS? I tried, but I don’t see any performance difference, whether it’s Quality, Balance, Performance, DX11/12. Sim says “limited by Main Thread” so common sense tells me my GPU still has spare muscles and it’s the CPU that is struggling. Is it the nVidia driver?
Yep, I am happy with my current Non-DLSS performance especially after SU10, but I’m just curious if anyone has similar specs as mine and got significant performance improvements with DLSS, 'cos why not?
I posted this elswhere, but will perhaps give you some ideas to consider:
12900kf/3080ti/32gb/5120x1440 Full Screen
ULTRA preset / 200TLOD / Live Traffic / No AI traffic /Vsync @ 40 FPS
DX11 / DLSS Quality
This gives me stutter-free 40 FPS 99% of the time. Will drop into the mid 30’s with the 320 at Heathrow or KJFK. These settings have the added advantage of lowering the GPU power draw by 50 to 65 watts…good for temps and good for environment!
If I turn off Vsync and DLSS, the sim runs between 50 and 65 FPS 99% of the time with the same mid 30’s with big airport/big airplane. Since I’m perfectly happy with 40 smooth FPS, I see no point in running it this way.
I haven’t used DX12 much as it’s not a smooth for me at this time. I’ll try it again when the new nVidea driver comes out.
Hey wilco3563, have you tried the newly-released nVidia 517.48 driver and DX12?
People are reporting much better performance boost. In my case it’s just about 5-6fps and only in certain areas where bottleneck is in GPU and there’s thick clouds.
Thats because you obviously did not understand at all what DLSS 3.0 is all about. It is basically a “hack” to get more FPS by simply rendering an additional frame based on some algorithms that does NOT use any CPU calculations, that is why you will get almost doubled FPS even in a CPU limited scenario.
The untold part of this “hack” is how it will work out for really low FPS situation (where it actually would make sense, no need to double 100 FPS to 200 FPS…), because for example all controller inputs still depend on the CPU. With DLSS 3.0 you might get 40 or 50 FPS but the sim will be laggy on your inputs simply because the “true” FPS would be only 20. I am really excited to see if and how this will work out.
Indeed this is true. The point here is that DLSS 3.0, in contrast to DLSS 1.0 or 2.0, does have a feature called frame interpolation. This means DLSS 3.0 will calculate additional frames between two key frames.
DLSS 2.0 is only a fancy upscaler on steroids. But if reducing the resolution does not give you more fps, DLSS 2.0 can’t do anything. Getting 25fps with the low resolution and upscaling it to 4k with DLSS will always result in 25fps.
In contrast on DLSS 3.0, when you have 25fps output in low resolution ,the DLSS 3.0 algorithm can interpolate additonal frames and bring up the fps to much higher values. The downside is input latency, because the input still has to work on the true 25fps, since the interpolated frames only exist in the video memory and they have no connection to the actual game engine - they are just interpolated between two true game engine frames.
