Well a couple months back I began having lag spikes, this all began when I installed the latest drivers from Nvidia. Therefore I went ahead did a clean install since I may as well have and installed Nvidia drivers ver. 260.89. They had worked well for me in the past so I went back to them after the clean install. Now every 30 seconds or so I still get lag spikes that last for approximately 5-10 seconds. Network has been reset and tested ping/in/out etc in MP games are perfect. System is perfect and not reporting ANY spikes in usage during game or overheating. Heck FPS in 60% of the games are normal, one game which does see a drop is TF2 which ranges from 60 to 30 FPS but appears more like 5FPS at times. System Specs Clevo M860TU Intel P8700 C2D Nvidia GTX 260M 6GB DDR3 Memory Resolution (1920 x 1200 but gaming on 1680 x 1050 (external monitor)) Temperatures are high but still well below the point where things should clock down. (fans cleaned/notebook cooler) Windows updated, ccleaner run, etc. AV of choice; ESET NOD32 Any help would be greatly appreciated this is really puzzling me to the point where I am considering reinstalling windows again but I really dont think it would be that effective as this appears to be a persistent problem.
