OpenGL game gamma cant be adjusted with the 3D full screen gamma option

Affects: Everyone who doesn’t use default gamma settings
Workaround: Use the Desktop gamma setting instead and that will adjust it
Status: Unknown, reported?
Messed up textures and backgrounds in older games, Carmageddon and Final fantasy VII for example (PM me if you have others)
Affects: Everyone
Workaround for problem: None
Status: Requires implementation of 8-bit palletized texture support (may need emulation as hardware doesn’t appear support it natively), if you wish to petition ATI to add this feature to the drivers

Possible method it can be done (suggested by Colouless) Emulating Palettized Textures can be done reasonably fast using Dependant Texture Reads or EMBM (which is just a simple form of depentant texture reading). You use the dependant texture read to emulate the palette lookup when the texture is being used. However, when using this method the quality is generally 'poor' or the speed is 'poor' since you can't use hardware bilinear filtering. You will have to use point sampling, or do all the filtering in a pixel shader (NOTE BY ME None of the drawbacks are really a problem as we are talking about a compatability mode for OLD games that would be running fast anyway and dont use pixel shaders for other purposes)
Missing VESA 2 support for DOS games and screen corruption

TVout and monitor display not saving settings when at different resolutions and flipping between them also lowers the refresh rate
Affects: 1 user confirmed (PM if you want adding)

Slowdown / stuttering in D3D/openGL with AMD MPx dual chipsets
Affects: Quite a few people (if not all).
Workaround for problem: START->RUN->SMARTGART and disable AGP reads/writes completely removes stuttering, or BIOS->AGP APERTURE SIZE down to 32MB which helps reducing the length of the stuttering
Status: Been getting better every Catalyst release since 2.3, but still 9FPS at times. Solved 10s pauses in 3dsmax5, common pauses in Blood Rayne etc etc.
Extreme slowdown with Silent Hill II using shadows, with AMD MPx dual chipsets
Affects: Everyone with 9700+ and AMD MPx?
Workaround for problem: Disable AGP reads/writes
Status – in progress?
Texture clamping in OGL not working for certain games Alice, Icewind Dale, Q3 Urban Terror Diablo II, Quake3 engined game skyboxes
Link ?
Use the Feedback form to request a compatability mode to fix this issue

Affects: Everyone
Workaround for problem: ATI's method works as it should, but problems where games were written for NV hardware only
Status: Unknown, reported multiple times
