Hi all.

I seem to be getting a flashing sky all the time when outside during daylight. Is this a known problem?

I'm also getting flashing white dots on the landscape.

nvidia? nvidia 4xx? If so rumor has it nvidia will patch the video drivers. To make up for Obsidian crappy programming. I can't believe they didnt test this game with one of nvidia newest cards....

Turn off HDR in the options menu... If that does not work some people had luck with disabling anti aliasing in the game option menu.

I have the 4xx series and it was HDR causing the flashes for me.

Yes it's a NVIDIA issue. GTX 4xx has the floaty spots. Other older NVIDIA cards have major slowdowns at NPCs.

Yep, 2 1GB GTX470's running in SLI.

I'll just wait till it unlocks then apply the patch (I'm from the UK)

Varying anti-aliasing did nothing for me. Turning off HDR and using Bloom cleared it up completely, but the game looks a little drab now. Hopefully those updated drivers will come along soon, but being Nvidia just released their latest WHQL drivers I don't hold out much hope of that. It is pretty surprising that this wasn't caught by Obsidian before release. I noticed it the first few minutes I played. No excuse for such lax testing.

The issue is caused by HDR + Anti-aliasing being enabled at once. The Nvidia driver profile for New Vegas is not updated to fix this yet, but the one for Fallout 3 is. The fix is to either disable HDR or AA, or rename your 'falloutnv.exe' to 'fallout3.exe'. This will force it to use the Fallout 3 profile, which correctly works with AA + HDR.

If you want to get really technical, you can download NV Inspector, which allows you to modify Nvidia profiles beyond what's possible in the driver control panel. You can use it to match the AA compatibility flags from the fallout 3 profile to the Fallout: New Vegas profile.
