[d3d9] Stutter after 30-60mins of game play (various games)

With both Sanctum 1 and Payday 1 I get massive stuttering after 30mins of game play:

Both games have this weird issue where the game has full FPS unless I start moving around with keyboard or mouse (I guess triggered by a scene update?)

Software information

Steam overlay isn't working either. Shadows seem broken in Payday (will file another bug report for that soon). using wined3d seems to crash Sanctum.

System information

• GPU: RX 580 4GB
• Driver:
• Wine version: Proton GE 6.20
• DXVK version:
