What's wrong with my video card?

Featured Replies

It seems lately everytime I run FSX I eventually get strange scenery effects like poles in the sky, huge gray areas, etc. When I refresh the scenery everything is OK but eventually the weird effects return. Sometimes a little window opens up breifly which has the term "VPU" and my hard drive spins like crazy!! I checked the event viewer and sometimes there is an error called ATI2MTAG. The error suggests I should update my drivers. I am using an ATI Radeon X1900GT card with version 8.4 drivers. I use XP SP3. I cleaned out the inside of my PC and made sure all my fans were working. I also made sure all cards were secure and connections were OK. I also use FS9 with no problems at all!! I have been using FSX intermittently for several years with only minor glitches, but over the last couple of months running FSX has been almost impossible!If anyone has had similar experiences I would appreciate knowing what you did to fix it. Thanks for any ideas!Airbus

I suspect you have the /3GB switch properly installed for an XP system. It's almost mandatory with FSX. But I did a Google search for "ati2mtag error fix" and came up with several possible solutions. One indicates you might be overclocking your card too much.Best regards,Jim

Jim:Unfortunately I don't have the 3GB switch installed. Should I download and install? I am also NOT overclocking my card, maybe something else is going on. Thanks for your help!Airbus

Nick's Tune Up guide has a discussion on how to implement the /3GB switch for XP systems: http://www.simforums.com/forums/forum_posts.asp?TID=29041.Also, I hope you followed my earlier suggestion of the Google search for "ati2mtag error fix". It has more suggestions for fixing this non-FSX problem.Best regards, Jim Young
