No, but if you reformat the C: Drive it can speed up everything.Or delete System 32, it takes up a lot of processing.
Haha my OS is on E:\
That's not possible.
It is if you have 3 partitions on your hard drive.
l4d2 minimums 3.0 so its going to be laggy
I see no reason why if you partitioned your hard drive your OS would get put on E/.
