TF2 vs HL2:DM: Team Fortress 2 Drastic FPS Drop - ati legacy drivers (Mobility HD 3470), ati 13.1

[kbarter-cz]

Hello,

I'm sorry if this issue was solved before, but I need to report drastic FPS drop in Team Fortress 2 (I presume orange box engine).

System is installed from Ubuntu 12.10 minimal, LXDE, openbox, because game was unplayable on other tested environments such as Unity, Gnome Shell, KDE...

I'm running TF2 on smallest possible settings (all to low or none), graphic card: Mobility Radeon HD 3470, resolution of game: 640x480. To clarify this, same card in windows performs without any FPS drop.

For easiness, I'm reporting what happens, average values: No players: fps 120 2 players: fps 60 4 or more: fps 15

In contrast to Half-life 2 Deathmatch, HL2 DM has no significant problems. HL2DM runs even on my maximum resolution (1280x800) with very small jitters, so I think there is problem in orange box engine. I am aware that also version of the driver can cause problems. Version of fglrx-legacy is 13.1, installed from makson96/fglrx

UPDATE: As I had chance to download & install Portal Beta, Portal's performance is same as on HL2: Deathmatch. I was even able to increase texture quality with small jitters. Off Topic: Portal has issues with portal depth, but I consider this as driver-side issue.

To solve bad performance in TF2, I'd like to ask you for some tips with contacting AMD and support. Steam (or Valve) has bigger power than one person in this case.

Hello @kbarter-cz, this issue was most likely vram pressure related. Source 1 games on linux uses ToGL internally, which translates directx to opengl on the fly and requires more vram than using directx directly. Although not supported, your best chance for a good experience on this hardware would be to run mesa and wine with gallium-nine support.
