PodHacks 4.0 can synchronize the 3Dfx Glide open/close calls to the main thread.
This should help to avoid the "grSstWinOpen Error" for DX9-based Glide wrappers.
Auto-enabled for nGlide and dgVoodoo 1+2 but might be useful for other wrappers.
The current nGlide versions release the textures during resolution changes (this
is a missing feature in several Glide wrappers) which results in damaged vehicle
textures. To avoid this problem you should use PodHacks 3.9a or earlier (prevent
all resolution changes). Download
