The game far cry 6 trail which can download demo free is a good test to show texture cache or pixelshader cache Problems. it also have a AMD Logo on start. Far Cry 6 use many Pixel shaders. RX 6500 XT get extreme slow after 18 sec in this video https://www.youtube.com/watch?v=PI64REAm1hc or when bench with same settings run 2. time without start the game new.
Did other developers also notice such strange big slowdown problems ? . you see windows offers me 20 GB VRAM and same as with virtual system memory management of windows windows or AMD driver should keep the most important need stuff in VRAM . the whole game need 4,2 GB vram so it is unbelievable that the GFX card for play the benchmark need all the 4.2 GB for every frame. so same as windows virtual mem system the GPU mem system can also remove unneedet from Pysical VRAM
In game when look on floor stay very slow. The gpu clock stay high but the ram clock drop. no too high temperature can see or to many power use. The much older gforce 1030 which i have have only 2 gb vram and also PCIe 3 x4 and work with 10-12 fps alway. The RX 6500 is when run the benchmark the first time faster with
50 fps . but on second run of the bench it get only 7 fps on Full HD.
I use latest Adrenalin driver, have test it with win 10 and win 11 and i have a i5 8600 H310 with pciee 3x4 with 32 GB RAM and SSD no Harddrives I try with or without texture format optimisation in driver. did not help
