Awful input lag in Isource games Ubuntu 13.04
In all source games I'm getting this unbearable input lag, making them all literally unplayable.
I have a 7670m+7660g on 13.4 AMD drivers

Same problem, when I play LFD2 fps seems OK but mouse input lag makes it unplayable. Tried setting raw input in options but it dose not work.
I on a Dell Inspiron 5520 with AMD7670M and AMD 13.4 driver

Hmm, I wondered if it was a problem with the 7670m, however I'm currently using the 7660g alone with the problem continued.

I also have this lag. It seems gpu gets behind in rendering - so it is more of a rendering lag than input lag. Try using fps_max with a number below your lowest fps - it helps since the gpu then catches on.

Noob question here: How do I set the fps_max?

In-game you can just enable dev console, press the ` key and type it in "fps_max 60" for example. For it to persist you have to write it into the config file of the game (config.cfg)

Same lag here. That is DotA2 and CS:SRC. Same GFX (7670) on dell vostro 3560.

I no longer have it in Ubuntu 13.10Dev with 13.8 drivers.

setting fps_max helps only if your card can keep framerate above this limit. To really resolve this you have to set "gl_finish" to 1

Have you guys tried disabling vertical sync in the video options?

Did any of you turn off OnDemaned? or try thr Beta Catalyst 13.8?

Install the newest AMD Beta drivers, the bug was fixed there. Although the overall performance is still bad.

It's at least bearable, though.

You mean the 180-200 fps in L4D2? Yes, pretty bad. Only the occasional hitching/jerky camera movement should disappear, and all would be fine.

Performance hits are worse on weaker cards. I get 100FPS easily on Windows playing L4D2 maxed, 1080p, and barely 30FPS with obscene amounts of stuttering on Linux.
