When opening up the in-game map, the following will happen:

queue sync count goes up from 2 to 12
GPU usage goes up from 4-10% to 89% on my 4070

Needless to say on some GPUs this will cause low performance and frame drops. Windows users have reported this does not happen on native, see: https://github.com/AlpyneDreams/d8vk/issues/76

The game appears to do an insane number of back-to-back surface locks for some reason, but I'm unsure if we can optimize any of that in any sane way.

d3d9.cachedDynamicBuffers = True does not have any noticeable effect in this case.

DXVK 2.6.2 shows about the same performance as 2.4 on my machine, varying in range approximately 25~30 FPS (depending on the map position?). Symptoms as described above, the amount of queue syncs shoots up. Intel Core i5-7400 w/ HD Graphics 630, Mesa 25.1.3, Wine 10.9 Staging. Game version is 1.04, with the official No-CD executable applied.

Thank you for confirming. Yeah, I expect it to be quite noticeable on an iGPU.
