[Nouveau] Steam Revenge of the Titans on Arch Linux - Garbage display

[Alen Skondro]

Hi,

I'm sorry if this is the wrong mailing list, but here it goes...

on Arch linux, I'm trying to run 'The Revenge of Titans' but all I get
is garbage (image links bellow) even the game worked perfectly two months
ago.

I'm using:

- Kernel: 3.10 rc6
- Mesa 9.1.3

OpenGL vendor string: nouveau
OpenGL renderer string: Gallium 0.4 on NVA0
OpenGL version string: 3.0 Mesa 9.1.3

How can I tell if this is a nouveau or a game issue?

Can I run the game in pure SW emulation (without HW accel)?
