I think I'm running from a fairly high native res to begin with, 3840x1600, which scales to 5120x2133 x1.78DL or 5700x2400 x2.25DL which are still rather taxing. At lower resolutions you may not see as much of a performance hit as what I'm seeing.

Oh can't wait to try that out in HLL since the standard AA implementation is pretty awful.

Quake 2 RTX 1.6 released and some new abilities are HDR and AMD's FidelityFX:

Nice. I have the game but haven't played it as yet.

Just tried it out. It's nice, as the temporal AA upscaler has kinda terrible motion stability.

Manged +/- 30 FPS @ 3840x1080, in HDR, FSR on, Res scale to 90%, GI to Low with 2 bounces. If I dropped the res scale to 85% I could bump the bounced to 8 and get 35ish fps. Or GI to Medium and Bounces to 4 also worked well. All playable for SP, not bad for a little 6600XT :)

I've been chatting with Blaire about Microsoft Flight Simulator and how it would be nice to have Dlss in the title. Been playing the title through Game Pass and usually not my cup of tea, but enjoying it. Blaire just shared this link and it looks like DLSS is coming to Flight Simulator in a future update:

DX12 improvement with DLSS and multiscreen is being worked on, Sim update 10 or later. They have an internal branch with this stuff already, and seem pleased with DLSS

Awesome.

Does DLSS work in VR?

Mangler Jan 26, 2022 11:20 PM

Yes, NMS has dlss+vr support.

demo Jan 26, 2022 11:30 PM

Sweet, cant wait to try it in MSFS

Good read. NV coming up with new ways to speed up RT performance without requiring more transistors. As always, NV leading the way..

This type of research is going to become more and more crucial as we go. We are seeing the power requirements skyrocket in order to continue performance increases; time for some creativity in the sector and finding ways to make the same amount of transistors more efficient.

Megaman Jan 30, 2022 05:33 AM

Shame they canít through something like that in a driver update.

As of now, looks like it's something that needs to be in the silicon. Maybe over time they figure out a software solution.

Currently playing Metro Exodus Enhanced and it looks great.

DLSS is Balanced and Ray Tracing Ultra.

I only go out in the wasteland in the day so far, so I'll have to wait and see how the Ray Tracing looks in the night.

Night is scary in this game:) .

Possibly the best RTX implementation so far.

I didn't know this..I thought most of them are about the closed system from nvidia.

Will Intel Alchemist have ray tracing?
At Architecture Day 2021, Intel confirmed that its upcoming Alchemist cards will support DirectX 12 and Vulkan ray tracing at launch, which comprise the vast majority of titles that support ray tracing available today. Ray tracing cores aren't all built equally, however.

Mangler Feb 2, 2022 10:09 AM

You know that nvidia is good at marketing when people think that dxr titles are using propitiatory nvidia tech.

LoL so true ^


Question: Does the NIS upscaling and sharpening filter work in VR?

There is OpenVR mod that supports both FSR and NIS. Allowing you to use either with all SteamVR stuff.

SIrPauly Mar 16, 2022 03:33 PM

Thought this was interesting with Dlss and NIS being offered by the developer:

I have to say that I have a lot of respect for DLSS as it enabled me to crank everything in Exodus Enhanced to the maximum.

Except for the odd ghosting, phenomenon such as pictures on walls popping in suddenly and distant flags seeming to flutter at a slower framerate DLSS is a good trade off to get RTX effects maxed out. The lighting and shadows in this game are superb.

The flags fluttering at a slower framerate is due to Metro's LOD. Can't control it unfortunately. It's saving processing power by having the things faraway render with a framerate cap.

I'd say the pictures popping in suddenly are also LOD related. Easy test would be turning DLSS on and off. I don't believe there's a setting for LOD directly .. probably an oversight from the game being on console.

You know it's a transformative feature when it forces their competition to offer something similar to compete.

Still would like to see things improve by tackling the performance hit with denoising, improve upon the artifacts at times with Ray tracing, improving more on subtle abilities like particles, and strong lighting and color contrasts

The title where Dlss shined the most to me was in Horizon Zero Dawn where 4k Dlss performance mode was clearly better overall than Native 4k+ taa

Yes, it's an excellent tool.
