I'm playing on a desktop not a laptop so it overheating still likely to be a possible problem?
When I got in tonight I started a game as an experiment to see how it was running and it was fine, nice and smooth. But when I began a proper game and started changing tactics, scouting players etc. the game suddenly appears to jump again when I play.
This would suggest that, now the latest graphics drivers are installed, it's not actually a graphics issue anymore but an issue with the CPU.
I'm confused because I would assume that taking it in to be repaired and restored to factory settings would have increased the speed rather than slowing it down.
