Patch for two issues.
Oh, I thought it was my graphics card being outdated that was the issue with an ancient GTX 560 Ti (I haven't really played games in a long time) on an outdated system (Win 7) and not being able to get a driver that's more up to date.
But reading this it seems that upgrading wouldn't necessarily help even. C317 still works perfectly fine, but can't get C327 to work no matter what I do (initialising WebGL fails).
