Team Fortress 2 Forum

It appears the bug that pops up in Left 4 Dead with this configuration also occurs in Team Fortress 2. It is reproducible by loading the Badlands map (any mode) and simply walking into the daylight area. The screen flushes to white and never redraws properly, even after being killed. It looks just like the issue with Left 4 Dead (text and HUD is seen but nothing else) but only occurs on certain maps (possibly only that one). I also had to turn off the Dynamics as the Full and/or Bloom do not look proper. None of these issues occur on ATI 2600HD. Has anyone else seen this issue? I haven't tried toggling to backbuffer as it only affects certain maps but I can if needed. It may not matter if this is a driver issue with this card and Snow Leopard.

What OS are you using?

I'm on Mac OS Leopard (10.5), and I don't remember having that problem before (though I don't play Badlands that often).

The OS Version I'm using is in the title (Snow Leopard - 10.6.1). I believe this is related to other issues with X1600 cards as it does not occur on my home computer with a 2400HD - it occurs on my work test computer which I use for development testing. You can also see this issue occur when playing any payload map, walk onto a control point after an enemy has captured it - the screen will flush red until you die or move far enough away (screen takes time to redraw).

I had a problem like this when they first introduced the sniper update, anytime Jarate was used the screen went all white and I couldn't see anything. This problem resolved itself after a while, so I'm not really sure what changed.

There's a bug on the Snow Leopard X1600 driver. If the game tries to read the back buffer with GL_EXT_framebuffer_blit, OSX will read the front buffer instead, leading to a feedback loop that slowly blurrs out the screen instead of showing the proper rendering. I have reported this to Apple as rdar://7121853 . Unfortunately, Apple policy makes it impossible for you to see the bug report, and NDAs prohibit me from talking about future OSX updates.

Workarounds:

• Use any other GPU(ok, kinda bad workaround)
• Downgrade to Leopard
• Disable FBOs in the bottles registry - will work around the bug, but kill performance in dxlevel 90 and 95.
• Try dxlevel 81, disable HDR in the in-game settings.

This has not been resolved as of 10.6.2

This has been resolved for me in the 8.1.3 version of CrossOver games, I can now also even load maps I couldn't before - like 2fort. Thanks a lot, guys and gals!
