System Specs: 3.4 Intel Pentium Abit motherboard 756 megs ram Gigabyte GeForce 6800GT Soundblaster Live! 24 bit sound card Windows XP Power Supply: Allied 450W DSL connection Mind you when i first installed this video card I was averaging 99fps on Cs:S... now when i stress test it i average 65fps if my computer has been off for awhile... and below 45 when its on for awhile and each test its lower. This change in fps all seemed to occur in a short amount of time, maybe a day or two.In game play i now average 15 fps during gunfights and even lower with smoke. In battlefield 2 i have every setting on low and or off and I can say without doubt that i have seen a fx5200 run the game smoother on higher settings. It seems that whenever the game gets intense (gunfights or fast mouse movement) there is a severe graphic lag i.e low fps. I thought my 6800gt was bad so i had it sent in to gigabyte, they replaced it and it runs the same as described above. Any help is much appreciated and mind you my drivers are the current nvidia drivers and i do not mess with my bios settings or system configs.
