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

Haven't you answered your own question?

it performs decent enough

 

[HankSc0rpi0]

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

 

[heatonpkmassive]

I would imagine you'll always get lag with MFG, especially at 3x.

It's a very subjective thing, only you can answer your own question really.

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

MFG is generally pants anyway and no substitute for raw performance. Maybe they'll improve it, but at present it's just something they've used to make the fps counter look good and sell cards. It's actual usefulness is still very limited bar a few games where you can get away with it.

The original Doom reboot game could run on a toaster but now it needs expensive graphics cards and fake frames.

 

[HankSc0rpi0]

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.

The fake frames themselves are quite good it's the lag I don't like.

Honestly...It's a fairly fast paced game and I couldn't see the difference between normal Ray Tracing and Path Tracing whilst playing it, so I stuck to normal and enjoyed the extra FPS.

 

[CaptainRAVE]

At 4K I actually found the performance hit just too big for too little visual benefit in such a fast paced game. That’s with a 5090.

 

[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

 

[heatonpkmassive]

2x can be acceptable in a few games, maybe this is one of them. Do you notice a difference in latency?

 

[Tinek]

Personally I only use FG when my FPS it already high, to hit close to that limit of my current monitor (4k 240Hz OLED). And I use smooth motion from drivers in world of warcraft as that engine sucks and drops to 40fps in places from 200+, that makes it seems very jarring - SM smooths the transition in such cases and helps a lot visually, where increased latency isn't very relevant.

That said, I've seen a bunch of tests online measuring latency with FG and MFG of various settings - it's not a big difference, most people likely won't even notice but only if the base FPS is already high enough (above 60 for sure). Going lower and it starts to be easier to feel but it's still very subjective, so it varies a lot between people. Some don't mind it at all and prefer smoothness increase, some feel and hate the increased latency. There are also much easier visible artefacts caused by FG at lower FPS - I tend to see them relatively easily if base is below about 70 but above that it's much harder to spot.

It can smooth things out, so a highly stuttering experience can be better or if it's implemented properly, it can work even at around 30fps base fps for those that aren't extremely sensitive to latency.

 

[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

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.

 

[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.

I know it’s not a 5080 but on my 5090 if I switch on MFG it microstutters like crazy. I’ve left it on DLSS balanced with everything maxed out and PT enabled, it hovers in the 80s-90s fps. 1% lows are high 50s.
