First - the caveat: I don't want to give up on this card yet. But - it is
really p***ing me off.

I recently got a CL TNT card to go in the following system:

C300a @450MHz
128Mb Samsung PC100 SDRAM
ABit BH6 mobo


After installing this card, I have the following problem:

Every time I try to use Open GL render in a game (Unreal & Sin Demo), I get
loads of wierdness as follows:

1) Unreal:
The game window opens as a white screen. If I move the mouse, then the game
appears - but in really strange washed out colour (Nali Castle flyby) -
black water, and sand coloured bricks etc....If I stop moving the mouse,
then the white screen reappears.

2) Sin Demo (set to default Open GL render)
The game runs fine - but I can see the console through the screen. It's like
the main game window image is flickering quickly and displaying the console
window behind it. Also - in the game, you can see THROUGH objects when it
flickers - as if  the z-axis control is way out on alternate frame rates.
You can see through walls for instance - all the clipping seems to be off on
alternate frames !

Reading the text in the console through the flickers yields this gem:

GL_VENDOR NVIDIA CORPORATION
GL_RENDERER RIVA TNT (AGP)
GL_VERSION 1.1.0

and:

WGL_EXT_SWAP_CONTROL NOT FOUND
USING GL_EXT_POINT PARAMETERS
GL_EXT_SHARED_TEXTURE_PALETTE NOT FOUND
USING GL_SGIS_MULTITEXTURE


 Now this HAS to be something to do with the problem - right ? It looks like
the game engine is looking for something to use to swap palettes with - a
shared texture palette maybe ? And when it can't find it, is using some
other resouces - and corrupting the video output while doing so ?

Anyone got any ideas on this ? I have heard of the white screen and wierd
mouse effect on theses ngs before - has anyone fixed it ???

As for different drivers etc, I have tried everything in vain - nVidia
reference drivers, newest Creative Labs drivers downloaded, new TNT card
BIOS (2.04.5), re-installing windows, re-inst unreal etc.... Absolutely
everything has been installed. And the card is not being overclocked.

And I also checked that the TNT and mouse were not sharing IRq as well - TNT
is on IRQ 10 and mouse is on IRQ 11 - so I don;t think that's it either.

I can run WinTune 98 Direct 3D and Open GL benchmark test without a hitch.
Plus - all 2D stuff runs great as well - fast as hell in fact.

It looks like I have some kind of Open GL problem here - but what is it -
and why do the WinTune 98 Open GL tests run OK ?
