v1.15.133
Fixed: The renderer was extremely slow when rendering transparency on low-end graphics hardware (like Intel IGPs) even when using pureD2 mode or turning off shader usage
Improved: Depth buffer reads will now be profiled and automatically disabled if they take too long
Improved: D2X-XL will fall back to alsa if pulse audio cannot be initialized
