This may seem a silly post but .....
I recently bought a P4 1.8Ghz, 256MB XP PC - a huge upgrade as I was running a Pentium 66 beforehand! Anyway, I downloaded DOOM thinking at last I will be able to play this game but ......... it doesn't run as it should. Jerky when firing, jerky sound!!! Surely it should run OK on this PC? Other more sophisticated games do. Is DOOM too old for the PC?
Any help appreciated.
