I have a game that requires DX11 but my GPU doesn't support DX11. I've been told by the game company that I can alter this to requiring DX10 or DX9 to run this game. Unfortunately, they're not available right now to walk me through it. Advice on the web
says to open the config file, and alter the DX11 line in there, but when I try to open the config file, my PC doesn't know how to. When I tried the 'search web for program' option, I ended up with REGSERVO and other similar 'snake oil' type products. I have
re-written config files in other games before, and it seems fairly safe to me, as long as I make an exact note of the original line, before tampering, so I can restore it to original if it doesn't help. So, how can I get my PC to open this config file?
