Just found out about this game. Seriously nothing is cooler than tweaking a 2002 game.
1. I updated game it to v1.2 and this gave me 1920x1080 support and mouse support
2. Used NTCORES 4gb patcher on the executable to allow executable to use more than 2gb ram if need be
3. Downloaded Crosire's DX8 to DX9 file and placed it aside executable. (Game wont even work on win10 without this lifesaver)
4. Installed Reshade DX9 and almost cried when i realized it worked. Even had depth buffer acess!
All i used was ambient occlusion, levels, bloom, and lumasharpen
Damn, seen the title and my mind immediately thought remake 8( Nice to see it still works, maybe it will show up on GOG some day. They just added Call of Cthulhu: DCotE with a patch that fixes all the bugs such as the notorious invisible sorcerers, and the skyboxing.
