thanks for the info
I currently don't have access to the compressed air. So in the meanwhile, am gonna do what u told me. I will leave 4 things open: the game, task manager, GPU Z and MSI afterburner and leave the task manager at the process tab (correct ? )
i will wait till fifteen minutes then observe which process that's using alot of memory eh?
but do i need to do any settings to the Core clock / shader clock ( whatever these are, but it sounds like overclocking my GPU to me..) do i leave them at default ?
