I had exactly this, I think its just making new shader cache as it goes along. If something happened for the first time (such as a new gun being fired) it would stutter for that action then never again even after cold restarts. Figured this out after spending this morning trouble shooting it. Destiny 2 was unplayable for half an hour until everything got cached, now I don't get a single stutter at all.Had my 6800Xt for a few months now. Still having an issue in all game in relation to Freesync/refresh rate etc.
Current specs are:
Sapphire 6800XT
AMD 5800X
MSi X570 Tomahawk Max
Corsair Ram 32Gb
NZXT Z73 cooling.
LG 27GL850-B 144Hz monitor
When running any game, if I don't use VSync or Radeons framerate limiter set to 144Hz, if the framerate goes over 144 fps the game becomes horrifically choppy. For example, running Warzone, I cant get upwards of 180 fps with my current settings, but it is unplayable due to the choppiness of the image, so I have to either turn on Vsync or fps limiter.
Am I doing something wrong , as previously on Nvidia and using GSync, it could run at over 144 fps and be buttery smooth. I feel as though I am missing something blatantly obvious. I have freesync turned on, fresh install of windows, tried different cables etc.
Any ideas or is this how it works?
Turn off 10 bit display in the radeon setting also, apparently it doesn't play nice with freesync, which is what i was using also.
Edit: I actually misread your post really badly but I'll keep this up in case others wonder why their new 6800xt stutters at first
My guess in your case is that your setup really dislikes leaving freesync range, and you should really be limiting frame rate to just under the freesync limit anyway. Of course if the picture frame rate is exceeding your monitors display refresh rate that's going to look choppy and teary. That's totally normal.
