Thanks but I already know how to use that.(Used that for Splinter Cell 1 since shadows were broken without it.)

Make sure your running the game in a resolution that is a multiple 640x480 and maintains an aspect ratio of 4:3 or 16:9.

The game will glitch if the resolution isn't set right. I posted a list of working resolution a few years ago, but I normally play in either 1280 x 720 or 1920 x 1080.

As long as it fits within those aspect ratios then the game should run fine.

I run it at 1366 x 768 and it works fine lol

Usually when it's not run in those resolutions you can sometimes get menu glitches. Like instead of having a transparent background in the items menu it will be all black or have stripes. Other times loading screens will glitch out for me.

I fixed the inventory stripes with choosing the 16bit colour from the "Texture Bit Depth" option along with 1366 x 768 16bit in the resolution option.

Can also run in software mode and everything works perfectly but I understand some people have trouble with it. But it works fine for me.

Hmm...that's interesting, guess whatever works best ha ha. :)

For some reason reducing to 16 bit colour causes color banding on textures on whatever system I try it. I rely on the multiply of 640x480 trick.

I'm currently playing it on a slightly unusual format Dell 5:4 monitor in 1280x1024 (highest bit setting the game supports). It displays without any inventory issues (black stripes) which it had when I tried to play it at my default desktop resolution: 1152x864

What I have observed is that the main menu load screen and FMV are all in 640x480. The FMV looks pretty bad. When it ends and loads the next level area or you use the main menu load screen, not the inventory Load/Save option, the swap from 640x480 to 1280x1024 causes the screen to flicker every time very noticeably.

Once everything is in 1280x1024 all is good with no other display problems that I've noticed.
