Hello everyone. I am using a snippet of code from the CodeBase to convert a greyscale to a matrix. It works great but it seems to be doing something to my video card and system. After about 30 seconds of viewing, my monitor goes into sleep mode as if the video card stops sending a signal. Really wierd. Has anyone else used this code and experienced any similar issues? I have a ATI Radeon 9000 w/128 and a 1g Athlon processor. I have no issues just creating a flat matrix, only when I call this function. I am also running the level with the matrix untextured. Is that the issue? I don't know, just fishing. Thanks in advance for any posts on the issue.
