Recently I build new configuration based on 3900X with 5700XT, all was fine until I started  "The Witcher" game-series. In first part (The Witcher: Enchanced Edition, Steam-version) I got problem with text fonts, as result - this game was finished on my old system (FX-8350, RX580). Now I start second part (The Witcher 2: Assassins of Kings Enchanced Edition, Steam-version)- no problem with fonts this time but I got abnormaly low fps in some places. How it looks - beginning of the game, fps counter show me 120-200+ fps and everything is fine, then in Geralt flashbacks about attacking of the castle fps drops to 30 and below (with massive dpors of cpu/gpu utilization), not everywhere but stable with camera view on some parts of location. In beginning it was Windows 10 1809 with 19.9.2 amd drivers and older chipset driver, now i update everything (windows 10 1903, amd 19.10.2, chipset and no effect in this case so i thought to create this thread, maybe I should create report to amd somewhere?

When i swap my RX 5700XT back to RX580 (Sapphire Nitro+ SE, 8GB) and launch TW2 - I got over 120 fps (RX580 is bottlenecking) in same place with same camera view. Just after replace new gpu to old, nothing more.

In my opinion its absolutely abnormal that newer RX 5700XT give x4 times LOWER fps then old RX580. Not everywhere, but my eyes just bleeding when i rotate camera and has fps drop from 140+ to ~30. Looks like AMD doesnt optimise well drivers for RDNA GPU to work with old DirectX9 games?

I have no problems with 5700 XT in GTA V, GTA IV, Monster Hutner World, Lineage 2, Assetto Corsa, Escape From Tarkov and Assassins Creed Odyssey.
