5850 running slower with SDD upgrade

Hi everyone,

A week ago I updated my computer with an intel 80 gb SSD as well as a 640 gb caviar black (for programs) from my 150 gb raptor (Clean install of windows 7 on the SDD). Anyways, before the upgrade I could play COD MW2 on max settings on my computer with my HD 5850 card and get 60+ fps no problem. After this upgrade, though, I am now only getting 30 fps, which is really cramping my game, haha.

Anyways, I've tried everything I can think of, like reinstalling graphics drivers from both the CD and the internet and installing motherboard drivers, but haven't fixed the problem yet. I tried using the raptor as my boot drive again, and the fps came back up. Do you guys have any suggestions of what I can do to fix this?

30 fps, sounds like v-sync is on?

No, it's not on. The game isn't pinned around 30 fps, but it averages 30 fps, being between 20-40 most of the time.

A HD can only really affect vid-card performance only while it's being read. Once a game is loaded into memory, then it shouldn't matter if your have a 5400 rpm micro drive or a 1500MB/sec SSD.

If your drive is causing performance issue, it should show up as very high kernel time.

Actually dependiing on the game as you play there is a constant loading\unloading of texture and mesh files form the HDD during gameplay as well so the speed of the hdd can make a big difference on some games !!
