Can I benefit from DLSS with my current rig (see specs)?

Hi there,

— 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? :wink:

Thanks in advance.

Also for me. DLSS ON or OFF, 0 difference. And they want us to believe that with the new RTX4000 cards, with DLSS 3.0 we will go from 60 to 120 FPS :rofl:

With DLSS 2.0 enabled, I go from 50 FPS to… 50 FPS lol

Ryzen 9 5850X
64 ram

Im in the same boat, CPU limited majority of the time, 12900k with a 3090ti at 4k, 2 cores get utterly hammered on the CPU.

DLSS does help however when its thick cloud, but I get worse FPS with DLSS on the ground as it again, uses more CPU to do the DLSS too.

Basically we don’t benefit from it because are GPU’s are not less performant than others.

That’s what I think too. Those running on older GPUs (2080 or lower) are the ones who got boosts.

But this YT video has about similar specs as mine (not sure if he runs 4K) but his DLSS settings have performance effects.

For me Ryzen 7 5800X + RTX 3070Ti 32GB ram
with DLSS the cockpit was blurried, TAA works very well.

For me i9-11900K and RTX 3080 no benefit as well.
The glass cockpits are ugly because of the blurries.
Otherwise no difference before/after SU 10.


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.

Ryzen 5 3600 + 3080 here.

I do get a good boost, but still looking to upgrade the CPU to make maximum use of the 3080.

Yep, I’m CPU limited too and hence see next to no benefit from DLSS. I did some comparisons in the beta here:

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.

Are you using DX 12 ?

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.


When reporting no benefits using DLSS, is that compared to TAA, and what render scaling?

I was using TAA at 80%, now I’m using DLSS Quality (I think that’s equivalent to 50% scaling) and the DLSS gives me about 5-10% more fps.
