Thank you! Surprisingly, this game does not load the GPU much. If lags start, it's probably the CPU. Wine runs in emulation mode, which is really slower, especially when it comes to multithreading. Probably the physics engine does not have the ability to work multi-threaded in emulation mode, most likely this is the lags reason. For me this runs smoothly under 16 ms with 50+ monsters on Windows with Ryzen 5 3600 and GTX 970.
