Built this computer less than 6 months ago. Has played all games maxed very easily. Recently, in all games including older games, I've been getting 1-2 second video delays.
A specific example:
I was playing Madden 2005 (very basic system reqs) flawlessly with everything at max. Now, whenever it goes from the play selection screen to the football field view, the players movements are very slow and chopy.
More generally, I'm seeing intermittent lag like this in all games in more random spots. It's annoying.
Anti-virus and spyware programs were clean. I de-fragged. I am playing the older games in compatibility mode. Everything worked seemlessly for 6 months or so prior. System temps ~35C, CPU temps similar at load. No unnecessary background programs are running. Just Windows stuff and ATI stuff from the GPU itself.
Anyone have any suggestions or questions that could help narrow down the culprit? Thanks!
