Description Sven Arvidsson 2011-02-13 13:42:12 UTC 
The game Tiny and Big is incredibly slow on r300g, almost the same as running it with llvmpipe.

The readme for the game states that minimum requirements are Radeon 2900 series (r600?) so it's quite possible this is a hardware limitation? But I'm filing a bug just to be sure.

System environment:
-- system architecture: 32-bit
-- Linux distribution: Debian unstable
-- GPU: RV570
-- Model: Asus EAX1950Pro 256MB
-- Display connector: DVI
-- xf86-video-ati: 6.13.2
-- xserver: 1.9.4
-- mesa: 04c5cc5b8bec1f34f2405b08fd0d9ed6bd70ea61
-- drm: 2.4.23
-- kernel: 2.6.37

Honestly I have no idea, but I am sure that the GPU is fully loaded in the game.
Comment 2 Marek Olšák 2011-02-22 05:37:22 UTC 
I gotta close this bug, because, as you say, the readme says that the minimum requirements are Radeon 2900 series.

BTW if you rotate the camera such that you stare at the ground, it's smooth. I guess there are too many objects in the distance, which slow it down.

Not sure what fixed it, but Tiny and Big is now fluent with master.

Awesome! 

The commit in question is d8361400b76dde6fb63df6c363b7dd59c5946e09 so it has already been suggested for 7.9 and 7.10.

Unfortunately master also introduced a segfault when HZ is used in Tiny and Big, I will file a new bug about this.
