[d3d9] - Senren * Banka (1144400): Performance Regression since 1.9

[Theucalyptus]

Description

Since DXVK 1.9, the game is very sluggish, ~20fps at all time while with older versions (1.8.1 works fine) the game behaved normally (constant 60fps, the framerate is locked by default, and unlocking it doesn't help)

That trace only contains 298 frames and finishes in 5 seconds. That's not long enough to investigate performance.

Please provide a longer apitrace that goes in game.

I can reproduce the problem with 1.9.

The current master version of DXVK causes a black screen in the game but after I fixed that, performance was fine again.

This build works fine. I was about to report the black screen issue as it affected many KiriKiri based VNs.
PS: sorry about the short trace, the issue happened even in the splash screen so I didn't bother to trace for very long, will do it next time.
