Today I tried to run Tiberian Sun on Win10 64-bit. Of course I encountered the missing menu screen issue, so I installed the TSPatch. Everything works fine except one thing. The loading times are ridiculous. New missions load very slowly and saved games load extremely slowly. Is there a way to fix this issue? The base game (without the TSPatch) loads very fast. I tried using both Origin and The First Decade versions of the game. The result is the same. I also experimented with different renderers to no avail.
