Hi.
Interesting problem with shader cache I have on one of my rig and don't have on another with indie unity game - Critter Cove.
Specs:
r5 5600
asrock b450m pro r2
rx 6600 gigabyte eagle
32Gb ram 2666
drivers from 24.20.19.05 to 25.2.1 affected
win10 pro 22h2 on both machines
chipset drivers 6.10 on both
Rig where no such problem:
r7 5700x
asrock b450 fatality
sapphire rx 6750 gre 12
32Gb ram 3200
In some in game situations CPU load spikes up to 80% from 25-35% on r5 5600 and FPS drops dramatically from locked stable 75 to 25-40, when I load that save file to another rig - all fine, CPU usage stay low. Sometimes I can load game and it smooth on problem machine, but mostly it's not. Video card in that game sleeping 800-1300mhz at peaks. Video ram usage very high 4.5 to 6.3 Gb. Rigs tweaked almost same, and software are same, clean installs both. I tried another windows installation on problem rig - not helped.
Interesting different is shader what created after game start and on exit between that rigs not same, once I replaced that file and game run smoothly as it should but next time amd driver or game itself replaced that shader files. I tried without success to enable shader caching in registry. Same high CPU load. I can achieve good FPS in any games what I play DX11/DX12/OpenGL on that rig, but not here.

Any thought please? What else I can try to do here to catch problem?
