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

[HankSc0rpi0]

I ran the built in benchmarks and it performs decent enough if I have DLSS on Performance and MFG set to 3X
Is this too much of a compromise ? Considering added lag and lower internal resolution in performance mode.
Previously I was playing on 4K DLSS Quality with MFG 2X
Running RTX 5080 and LG C4 42 inch which is capped at 144hz
Thanks

Yeah but there is a little lag and performance mode is an internal resolution of 1080p, so wondering is the trade off worth it

 

[HankSc0rpi0]

True enough, just gotta play and see Thought there might be a consensus on whether mfg is pants in Doom though. Thx.

My eyesight is not the best. I'm not even sure I will notice the fake frames. Will give it a good go and see.

 

[HankSc0rpi0]

Yeah I tried 4k DLSS performance Path tracing 3X MFG and got much the same performance as 4K DLSS quality Path Tracing off 2X MFG. Can't decide which is better

 

[HankSc0rpi0]

Well I tried it and 2X MFG is ok. Not noticed latency at 4k DLSS Quality PT Off on my 5080. That's how I'm playing now.

PT On, isn't for this GPU. Base frame rate is too low with PT on. With DLSS Performance, you need 3XMFG to make it playable, and it just doesn't feel right.

Guess I need a 5090 to play that way

 

[HankSc0rpi0]

I found I had to use PT and 4K DLSS performance with 3x FG to get good frames. And with PT off I could run either DLSS performance with no FG or DLSS quality with 2XFG to stay around 120fps. With an RTX 5080. Still can't decide which of the 3 options I like more.

 

[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

 

[HankSc0rpi0]

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)

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'
