Anyone know any good Pc FPS games that are online and free?

Unsure why my pc games are running slower.?

• I have a hp laptop, bought it new about 2 years ago. When I first got it, It ran all of my video games fine (HoN, LoL, SC2, CS, even Crysis on med, low settings). I would get avg of 50-65 fps in most of those games consistently. After about a year and a half, I noticed a lot of my games were running slower. LoL, and HoN, most notably, I was getting 20-30 fps whereas i used to get 60 fps. Any big battles simply were unplayable, bringing my pc down to 0-5 fps. I figured that maybe my laptop was bogged down from a lot of downloads and games, and miscellaneous programs i had installed but rarely used. I freed up a lot of disk drive memory, no noticeable improvements. I decided to update all of my drivers, no improvements. I defragged and no improvements. I uninstalled, reinstalled, ran at lower settings, my games were slowly becoming more and more unplayable. I wasn't sure what else to do, and in order to figure out if it was a hardware failure, I reset my laptop to factory settings. Sure enough, on this clean slate I installed a few games again and they all ran perfectly fine at 60 fps average, no problem. Everything was fine for about 4 months, and now im running into the same problem, sooner than i had expected. I was being extra careful not to download anything unnecessary although i was expanding my music collection because I had lost everything from before. I know very little about hardware and what to make of all this. I really am not sure what I can do to fix this problem without doing a complete factory setting reset again. Anyone know what is going on here? Specs: running vista x64 based PC NVIDIA GeForce 9600M GT (Approx.

• Answer:

  It could be antivirus software. That always runs in windows, and can use a ridiculous amount of your CPU and RAM. Also it could be a cluttered registry, from installed programs that clog it, or uninstalled ones which have left traces.
