Might get a 3080 if a good deal comes up tbh mate.
My rate is 500ms.
Yep I would expect your FPS to be higher with RT on, I'm sure that will change if you toggle it off like I did though half way through.
My GPU is obviously overclocked and 6900 XTs will overclock very well if cooled appropriately. Adding another 15-20%+ over a stock 6900 XT is easily possible due to the low power draw so plenty of headroom there.
I watched that video and honestly it looks like a possible local system issue.
What I noticed is that Jansen user looks to have manually overclocked the CPU to 4.65Ghz. However, in parts of the benchmark all but two of his CPU cores are operating at the base frequency, which is 3.8Ghz. See specs
here.
By running an all core overclock he is reducing system performance as if he had left the CPU at stock, or even just used Precision Boost Overdrive, many of his CPU cores could be operating up to or near 5Ghz instead of 3.8Ghz-4.65Ghz.
That's a problem and should not be happening. Is that definitely the cause? Don't know the game is not that heavy on the CPU so perhaps not but it's a red flag to me that something is not right with his config.
If it is not that, then my next best guess would be it's an old driver/bios/game version issue. That video was uploaded in Jan 2021 so might be that.
This is the problem with taking random videos on YouTube IMO, we have no idea if their system is even stable or what state their OS is in.
