I run the benchmark successfully with DXVK on windows, so I compared all my tests.

Here my results.

System:
Linux Ubuntu 20.04.1 kernel 5.8.7 + Mesa 20.3
Windows 7 + AMD driver 20.8.3
i5-2500 + RX 5600 XT overclocked

I'm actually impressed by the opengl performance. I would have expected a bigger gap.

Here's the Gigabyte RTX 3090 Gaming OC running at stock on Ubuntu 20.04.1 with an Intel Core [email protected] all core and DDR4@3600Mhz with tuned sub memory timings. I'll get to overclocking the 3090 in the next day or two...

Quoting: The_Aquabatdo you guys think that nvidia will release a TI on this generation?

They might do another "super".

Quoting: The_Aquabatnice score! congrats!
I did the maths and it's 31% faster than your previous 2080TI.

The RTX 2080Ti benchmarks I've posted here are using an overclocked 2080Ti. Comparing RTX 2080Ti at stock (59.47 FPS) and the RTX 3090 at stock (83.59 FPS) the uplift is 40%

I had a tinker last night and overclocked the RTX 3090 to gain 5% over the stock 3090 performance I also tuned Ubuntu 20.04.1 which delivered an additional +40 points on top of the overclocks alone, and game-mode was enabled.

Intel Core [email protected] all core and DDR4@3600Mhz CL16 with tuned sub memory timings

• +210 Mhz GPU Clock Offset (1935 Mhz - 1950 Mhz)
• +200 Mhz Memory Transfer Rate Offset (9950 Mhz or 19900 Mhz @ double data rate)
• +20W Power Limit (390W target)
• 100% Fan duty (both GPU fans)

NVIDIA Settings tweaks

• Force Composition Pipeline - Disabled
• OpenGL Image Settings - High Performance
• PowerMizer Preferred Mode - Prefer Maximum Performance

isnt the CPU the bottleneck for 1080 on a 3090?

Quoting: mylkaisnt the CPU the bottleneck for 1080 on a 3090?

Not for Superposition 1080p Extreme. It's a GPU killer.

you might get better results OC'ing the memory more and not clocking the GPU that much, will have more headroom for the powerlimits and memory OC seems to help Superposition a bit more :)

Nice beast btw! Just insane power usage.

Changed the thermal paste on my 2080 Ti today. Not 3090 levels, but a reasonable uplift nonetheless.

So, I gave it go:

• +180 Mhz GPU offset
• +950 Mhz memory offset
• +20W power limit
• 80% fan duty
