I successfully installed the Unofficial Arcanum Patch, High Resolution Patch (1.5) and DxWrapper, put all the settings according to what's explained.
The game itself runs alright, but the start menu is extremely laggy when hovering over Single Player/Multuplayer/Options etc. and the same happens when in-game when pressing escape to save for example.
I've also tried adding "-no3d -doublebuffer" to the launcher to see if that changed anything, it didn't unfortunately.
I've not been able to find anything on this, wondered if someone knows how to solve this.
