I have just upgraded my PC tot he spec below. Mboard, Memory and Graphics card (Geforce 5600 256MB) are brand new. Windows installed and working like a dream but....When I play FS2002 (and 2004) the flight usually pauses after take-off. The when it resumes, I get blocks or huge square pixels (usually transparent) all over the display. When I quit the game and restart, the blocks are everywhere. In fact this problem happens with a couple of other games (eg Tiger Woods Golf) - most noticeably after the FS crash/pause.I have removed and reinstalled all the latest drivers for the Chipset/Graphics/Sound etc but to no avail. What's more, the landscape is very "Shimmery" and horrible to look at - I never had this problem with my older, and slower system. IS there any known solution to these problems - please let me know if it soudns familiar.My system isAthlon 3000+Aopen MBoard (Nvidia n-force chipset)Nvidia 5600 256 MB 1MB DDR 400Windows XP SP1

try a different set of NVidia drivers. The latest(Beta?) are in the 55.xx range. The 53.03 ones work fine for some people but not for me - I've stuck with the 52.16 as giving the best results on my setup.Some swear by even older issues 45.xx etc. Dave

Adjust AGP aperture setting in BIOS. With 256 meg of GPU memory you can reduce the AGP aperture to 64-128meg, whichever runs smoother.Allcott

thanks for that...my current aperture is 64...shall I change it to 128 - and will this have any detrimental effects on performance or stability???? I've always wondered what this setting is - and therefore never changed it before!Very grateful fro your advice

I had trouble with 45.23 under W98SE until I selected in the card performance settings an AA of 4x. Other settings caused problems. I now use 53.x without problems. I have AA turned off in FS.Look in the cards tab for advanced settings.Using DX9.0b.

This can also be symptoms of a faulty graphics card, especially if the problem spreads to your desktop or even worse the boot up screen. David

The AGP Aperture is the amount of memory reserved for use by graphics outsid eof the memory on the card itself. As you have, like me, a card with 256meg of onboard RAM it is extremely unlikely that you will need much memory on the CPU. Howevre, also like me, you have problems with the lower settings. It is only a matter of seconds to change it then try the sim and see if things are better or worse. There should be no stability problems and performance should increaseYou should also change the FS9.cfg setting to read:TEXTURE_BANDWIDTH_MULT = 400(This is far higher than the very conservative default setting). Finally, ensure that your graphics card is using AGP Acceleration at the fastest level for your mobo - the problems you describe can also be caused by an AGP card running in un-accelerated PCI mode.Allcott
