Hi guys :) just wondering... is anyone playing with an ATI card? Dont know about the nvidia,but anyway without v-sync setting in the option,the game makes the usual v-sync line glitch everytine the screen scroll. Has anyone tried to force v-sync from the catalist to see if that fix it? Didnt had time myself to test it,the game is just been releasead and i got extra shift to do at work :/

    Works fine using forced v-sync on ATI card for me :)

    Yeah, I forced it on in the drivers. This is one thing that really ought to be in the lackluster display options in-game.

    I can see dumbing down the graphics options for other platforms (i.e. it will probably be on by default on iPad / Android), but on Windows VSYNC has always been an option. And we have to contend with driver preferences that establish the system default state. ** Come on Overhaul, it's not safe to assume that a system defaults to VSYNC on in Windows!

    Worst part about this though, if you force V-Sync on Nvidia cards, you get unplayable flickering on the screen. SO it's either flickering or screen tearing, unacceptable really.

    Do you have a way of disabling Triple Buffering on NVidia cards in OpenGL? Triple Buffering in OpenGL works differently (has never been officially exposed as an OpenGL feature) from Direct3D (where games are free to turn it on or off as they see fit), so it's almost always a driver option that has to be enabled or disabled.

    This is a common problem because of the way Baldur's Gate exchanges the front / back buffers... adding a third buffer into the mix causes undefined results (which are effectively flickering). If you disable triple buffering it should fix the problem right up.

    Hope this helps.


    ** I think the real solution here would be to stop using performance hacks related to manual buffer swap management, they almost certainly do nothing meaningful on modern hardware.

    This issue crops up again if you use third-party overlays such as Steam, where parts of the UI that don't need to be redrawn are never marked "dirty", so you wind up seeing a flickering Steam overlay until you pull up the map.

    You hear this, Overhaul? :) **
