i just got the game yesterday and I was playing it and a little after i would be moving or flying or something and like gray and silver would appear in the game and if i look towards it the whole screen turns,its not the game itself turning gray or silver but like images in the game,i tried restarting and reinstalling the game but it doesnt work,i can play for a little bit before it does it but then it will,i have battlefield 1942 and both expansions and they run fine and it doesnt happen on those,everything on vietnam runs smooth i can play online and everything but this gray and silver appears and i cant see,i have a celeron 2.4 ghz processor GeFORCE FX 5200 128 mb video card and 640 mb of ram my celeron is not a fast as some people's but it works for any other game,like i said it runs fine with 1942 and everything else runs fine on vietnam and it runs well for a while then it appears,can anyone answer why?
Do you overclock your video cards? Checked the temp while playing the game?
I agree with spyder, its more than likely than any graphical glitches are heat related - overclocking generally means more heat....
Other than that, when did you last update you drivers for your graphics card?
