Doom Dark Ages - Is Path Tracing feasibly on RTS 5080 with 4K DLSS P MFG 3

[HankSc0rpi0]

Haven't noticed Micro stutter but have settled on mfgx2, DLSS4 quality and PT off. I can notice weirdness with mfgx3 so no PT for me until I get a 5090

It's a DLSS 4 game, don't need to be using Quality mode when your output res is 4K, use Performance for the fps uplift. Visually it will essentially look identical even in motion. With DLSS 4 you can almost forget everything from past upscaling mode experiences as they don't really apply any more. Preset K (Transformer model) is excellent.

I was playing Dark Ages on a 4090 with PT and 4K output with 2x FG without any issues. Reflex handles any latency concerns in this implementation.

I assume DLSS4 is built in and you don't need to use latest or preset k via Nvidia driver. I have opted for DLSS4:quality anyway

If the game shipped with DLSS4 support then yes you don't need to do anything, it's only with games that originally did not ship with DLSS4 where you need to tell the nvidia driver to use Preset K, can be done a number of ways but the simplest is via DLSS Swapper app which handles the presets etc fully.

Here is my DLSS Swapper view for example:

Thanks for the tip. Only have Space Marine 2, Diablo IV, and Doom Dark ages installed at present. All support DLSS4 natively now after recent updates, and reflex ( have to turn on mfg for reflex to work in SM2 though). I turn on v-sync globally in driver (never in game). and the LG C4 is g-sync compatible. Only set frame limit 3 frames below max refresh if gane not supporting reflex. Zero tearing, microstutter or coil whine to date. Generally use DLSS quality.

For games not supporting natively I might try DLSS swapper instead of using Nvidia driver DLSS override to latest (which I think is preset k)

The only game I found where Preset K did not work (which is the transformer model) was Indiana Jones if you update the DLSS DLL files, it will just use Preset E even if you force Preset K in swapper or any other way. You have to drop back the DLL versions to 310.2.1 as anything newer seems to cause the game to only use Preset E.

Interesting, Gemini says Indiana Jones and great circle supports DLSS4 transformer model natively. Haven't tried that game yet

I assume setting preset k in the driver is the same as selecting 'latest'

 

[mrk]

Yeah if you didn't manually change any DLL files for DLSS then it should use transformer model out of the box. And yes latest would be preset K.

I think the latest NVidia App allowed this for all titles, you can now set overrides for DLSS where it just uses the "Latest" version of DLSS, even on older cards the override should work like my 3080. DLSS has reached the point where the upscaling quality (internal render resolution) means a lot less than it used to.

My general advice with image quality now a days is that it's all personal preference, if you're struggling to personally see a difference then just go with whatever is fastest. When IQ is concerned I just ask myself "If I was given these images side by side in a blind test, how would I rate them, and how sure would I be of my rating" If you're really unsure about your answer then they're close enough it doesn't really matter.

It's always subjective with these trade offs, asking other people if they can notice a significant IQ difference is usually pretty unhelpful.

The only objective right choice with PC graphics is turning off motion blur

I'm currently playing this game now. It's very taxing on the GPU. I've had to put a mix of graphics settings to get it to run 70-100fps.

It looks great but there is a lot more graphics options I could crank up.

Strange because normal they optimise these games for FPS. Where as here they seem to have an engine that is a little too heavy for current gen hardware.

It's path tracing and full hardware RT, there is only one GPU vendor where it's going to run properly on currently and it is highly optimised.

It seems to run about the same as any other PT game, I'm not sure from where the whole "super optimized" praise is coming from. It is snappier, less laggy, true, but that's about it. Textures/assets also don't look that great.

 

[mrk]

That is what optimised is, excellent frametimes, framerates consistent, no bogging down or stutters etc, all signs of superb optimisation, which cannot be said for anything UE5 related.
