Description Stan Staykov 2018-07-09 20:10:15 UTC
After upgrading from mesa 18.0.4 to 18.1.0 severe stuttering occurs in games like Baldur's Gate: Enhanced Edition and System Shock, and renders them unplayable. Downgrading back to 18.0.4 fixed the issue. As of writing this post, the latest mesa version does not fix this issue.

hi. Could you plz clarify, what System Shock game you meant? New one, which wasn't released yet? Or some old game?
Asking because I found demo of new one - https://drive.google.com/file/d/1zcBTkDP-ulMYprse2vvdlOHk7BTTVwWg/view
and it quite slow even on my 530GT :)

I meant the 1994 and 1999 games 1 and 2 respectively.
Notice that I mentioned that downgrading back to 18.0.4 solves the issue, therefore it's not a hardware problem. My cart is kind of slow, but it's good enough for old games like Baldur's Gate and stuff like that.

I highly recommend trying to build mesa from git and doing a git bisect from the 18.0.0 branch point until the 18.1.0 branch point.

There are not may devs actively working on the r600 driver and bisecting the bad commit will substantially increase the chance of someone actually fixing this issue.

oh... my bad, yesterday I was sure that I saw here Intel HD3000 :( And I had exactly that GPU... Do you have any intel card to check the issue (whether it actual or not on it?)

Can't confirm on radeonsi. System Shock 2 from GOG runs smoothly with mesa 18.1.2. Are you sure you also have 32 bit gl libraries?

Reassigning to r600 as it looks like this is probably a driver specific issue.
