Openra crashes in multiplayer mode under Linux

[ghost]

When playing Openra (20120315, stable) under Linux (Linux Mint 12, kernel 3.3) using the Cg renderer (OpenGL doesn't work) the game crashes after 15 minutes or so when playing in multiplayer mode.

dmesg says:

Playing in singleplayer mode works fine even with lots of bots and when playing for quite a long time. I've had this multiplayer problem with previous kernel versions, too. Is this a driver bug or a bug in the game?

If you're getting GPU hangs, then there is a driver problem. We may be doing something wrong to tickle the bug though.

matthias1, what version of nvidia-cg-toolkit do you use?

[ghost]

The version of nvidia-cg-toolkit is 3.0.0007, the one supplied with Linux Mint 12/Ubuntu 11.10

[cerebrum]

Well, you can try a newer version at least:

I had problems with nvidia-cg-toolkit-2.1.0012. OpenRA even doesn't start with it. But it was no that problem with nvidia-cg-toolkit-2.1.0017. So, you can try other versions of it too...

[ghost]

Ok, I'll try a newer version...

I tried the latest version of nvidia-cg-toolkit, but it didn't work out. As this is probably a Mesa bug, I'm closing this bug.
