Ah. I forgot ow2 is on steam now, so I assumed you were running it as a non-steam game. If you installed via steam, your deck should have downloaded the shaders so they don't need to compile... So then this can't be the issue.
What is stable to you? I put mine on a combination of medium and high settings and I get 45-60fps. If you need rock solid, probably play on low at 50fps cap.
I’m expecting/ looking for less stutters, a higher average than ~38, and a higher max fps than ~54 I guess. I’m baffled why fsr seems to do nothing for my frame rate.
Fsr isn't a magic bullet. Try setting everything on potato, fsr off, yand see how it runs. Should be like 50-60. If it's still giving you trouble, then something is wrong.
So you’ll get stutters no matter what version you use until the shaders compile. Play a few games, load into the training area with every character, and it will get up to a decent 40-50
