Counter Strike: Source caused me to have a WHOLE LOT of fragmentation on the computer. I have run the defragmenter, and it says it couldn't defragment those files. What can I do to fix this, because I believe it is what is causing a lot of lag in C&C Zero Hour and CS:S offline, even though I have it set to run with -heapsize 512000, -dxlevel 70, and something else to help it. Online it runs about 20, but because of my specs, I am not sure it is possible. Oh, btw, I have everything set to low at a resolution of 1024. Thanks! P.S. attached a txt document from defragmenter.
