Arrgh!!
I've upgraded my video card to an ATI Radeon HD 5770, and now SC4 RH will not run. Instead, I get a dialog box with the message I put in the subject header.
I run MW 7 64-bit on an AMD X2 240 dual core.
SC4 RH is running perfectly on my Vaio with the same software and a different ATI Radeon. As the Vaio's CPU is an Intel dual core, this means that the problem is either with my AMD CPU or with the new video card. Needless to ask, I have the newest ATI Catalyst (9.12) running.
Anybody else have the same problem? Solutions?
Many thanx in advance.
