40 series MFG. Does it actually work as well? I have my doubts.

I see this has been modded to work, but I've been reading feedback and experiences about performance and the numbers don't seem to add up for me.

For example:

\*Works great on stalker 2 on 4090

No fg = 170 fps

4x= 290 fps

6x=370 fps

Feels fine looks fine with dlss quality and dlaa\*

This is not working well at all. The performance cost here is absolutely insane and not \working great\. This received number of up votes as well.

Do 40 series owners just think this is normal because of no prior experience? Are latency values actually in check?

I see stuff like this (and other posts) and I get the sense it has a rather prohibitive performance cost that is actually nothing like Blackwell.

Or has it been fixed? Does anyone have a comparison between say a 4080 and 5070Ti to show performance regression and latency?
