Bad screen tear in HL2 Portal

[mateus]

Hi,

I've just installed Portal on my MBP with ATI X1600 (128mb) running XP SP2 via boot camp. While I've been able to play games like Far Cry with all settings on max without any problem cool, Portal suffers from bad screen tear, even if settings are set low.

Could this be a driver issue - I'm using the Apple drivers as I assumed these would be best?

Or perhaps it's just a problem that this game suffers from.

Cheers,
M.

EDIT: I should have put this thread in 'Apple Games'!

Have you tried updating your ATI drivers? I know Valve, creator of Steam, tends to have issues with ATI cards. Best to search their forums for any issues retaining to your computer.

I've just tried the Omega drivers & they've helped - still tears but not as much & seems smoother.

If you type "Portal screen" into Firefox's search box it suggests "Portal screen tearing" so it must be a problem although I can't actually find much info.

Screen tearing usually means too many frame rate per second. Look at your frame rate and see whether that's happening. If your frame rate is really high, try enabling
- Triple Buffering
- VSync
