Xess on 6700XT running worse than without?

[isolated1]

I tested XESS on and off in both 2560 x 1440 and 4k, and in both quality mode and ultra quality mode, the game runs at a better framerate average in the benchmark then without XESS. Anyone know why that is? I have a 6700 xt and a ryzen 7 5800x and 16 gigs of ram,

Native 2560 x 1440 without XESS - 129 fps
1440p XESS Ultra quality - 107 fps
1440p XESS quality - 118 fps

4k no xess - 71 fps
4k xess ultra quality - 57 fps
4k xess quality - 65 fps

Same with rx 590
Native 1080p: 60 fps
Xess UQ: 44 fps
Xess Performance: 37 fps

Basically the fastest code path for XeSS is only present on Intel Arc GPUs.

The other 2 code paths, DP4a (what RDNA2 can use) and SM 6.4 (what everyone beneath RDNA2) can use is slower than the CMC code path.

Nvidia can use DP4a on Pascal and newer and SM 6.4 in Maxwell and I think Kepler.

Same here. This basically makes it useless for AMD and lower NVIDIA cards unless you want to use performance mode. This needs FSR 2.1 instead.

It's so unfortunate they haven't got FSR 2 mod working in Shadow currently:(

This guy did a benchmark on 6800XT... and the FPS Boost is remarkable.
Although it's true about DP4a... but you should also get some FPS Boost.
There Seems to be a issue depending upon the system configuration or Drivers.

[Cry Warhead]

GPUs that support DP4a instruction can run XeSS, just with a slight trade-off between image quality and/or performance.

Intel XeSS compatibility

* Intel Arc Alchemist (Xe-HPG)
* Intel Xe-LP integrated graphics (11th-generation mobile)
* AMD RX 6000 (RDNA 2)
* Nvidia RTX 30-series (Ampere)
* Nvidia RTX 20-series (Turing)
* Nvidia GTX 10-series (Pascal)

Hint: disable motion blur for testing or always.

I have a 6800 XT as well and most people will lose FPS when they enable XeSS at the Ultra Quality preset. I retested and found out I tried this without Ray Tracing enabled. With Ray Tracing enabled I do see the boost he is seeing, which is honestly not too great. I felt like even the FSR 2.1 mod for Cyberpunk 2077 helped me out way more with Ray Tracing enabled. Without Ray Tracing enabled I do see a drop in FPS using XeSS at Ultra Quality compared to native. Not really impressed to be honest. Maybe this is a game that doesn't scale well with resolution and that's why we see these results.

Without Ray Tracing - Not using the benchmark though (don't have time):

Native 3440 x 1440 without XESS - 116 fps
3440 x 1440 XESS Ultra quality - 110 fps
3440 x 1440 XESS quality - 121 fps

Tried it for the lolz in 4K on my 5700 XT:

Native 4K: 41 fps
4K + XeSS Performance: 40 fps

ROFLMAO.

I tested without ray tracing though. Maybe I will try with ray tracing also.

[isolated1]

2560 x 1440 with Ray tracing and XESS off - 70 fps
2560 x 1440 with ray tracing and XESS on - 67 fps

still get worse framerate with it on then with it off.

2060 Super:
4k native: 20-30fps
4k dlss performance: 60fps
4k xess ultra performance: 1fps

anything above 1440p in this card runs at 1fps with xess

RX 580 8GB, in-game benchmark:

1080P tweaked settings: 87fps avg, 13634 frames rendered, 100% GPU bound.
Min/Max FPS: 73/142
1080P exact same settings + XeSS "Performance": 47fps avg, 7460 frames rendered, 94% GPU bound.
Min/Max FPS: 44/57

I uh.. tested this a few times on each "performance" level.. lol..
I have screenshots of these.
In the screenshot, it shows the GPU being the cause of the frametime difference, CPU render times (R7 1700) are still in the hundreds (130-415).

[Sp8i]

The sottr Benchmark runs the cpu and gpu at max together so it really is meaningless.

I think the XeSS is currently just a software render for some cards. The XeSS part of the frame render (which is not the whole thing) will in theory take 4x (or more) longer than an Intel GPU.

6900xt here, xess performance setting gives 2x the fps if raytracing is enabled
ultra quality gives a (small) fps boost
