8800gtx using 163.75's. all the options in the nvidia control panel are set to app controlled or high quality options and in hl2 i maxed out everything. i cant remember if i had this problem with previous drivers since i just recently installed hl2 again when i bought the orange box
squeeling during gaming, evga 8800gtx. i think its coming from either my mobo speaker or the card. nothing is overclocked. i use headphones so they block it out pretty much so ive just ignored it
