The new Space Marines 2 update brings quite a bit of features ( probably why Nvidia released a game ready driver for it but not AMD ).
First of hats off to the devs for upgrading us to FSR 3 and including frame generation in menu.....
Im super familiar with how this game runs on my 7900xtx, aside from having to turn the 4k texture download from ultra to high ( ultra simply fills up the 24gb of vram eventually then it's stutter time lowering that texture resolution to high keeps it'd around 16gb or so which reduces stuttering).
I haven't had frame rate issues in this game only stuttering but with the new FSR 3 mode as well as DLSS modes, it brought my system to its knees and once again I had to drop back a game to 1440p....I see now why Nvidia released an optimized driver ahead of this update ( we can't even get one for games much less updates they just totally own AMD in support)....
The frame generation in game specifies it's only for Nvidia, i think by the verbiage I read, however when i turn that ON ( even while forcing asmr2 adrenaline side ) it somehow helps us as well smooths out a lot....
We could really use an update for this co promoted game, that has AMD on it everytime it's started when there is a jump in features like this, my card never had frame issues just stuttering when vram was full on ultra but it won't run this update maxed....and wildly Nvidia frame generation is what helps...
Hire some driver devs you got to do better, this is an amd showcase game and Nvidia just flatlined you.....
But try frame gen on if you have low fps even though it says it's for Nvidia in the game menu I helped me...
