You need to check the Phoronix Test Suite numbers, for a number of games on all but the latest AMD hardware the OSS drivers are actually faster than the Catalyst ones. One area where the OSS stack is functionally less than Catalyst is OGL 4.3+. I too use the OSS Radeon drivers and find that they are within a few percentage points of Catalyst numbers and occasionally double digit faster.
OSS drivers for the latest AMD hardware (<1 year old) is hit and miss.
EDIT: clarification
- dogma1138 11y agoI can check what version I had in SteamOS but 20-30% performance difference in modern games between OSS and closed source AMD drivers as far as 2-3 weeks ago goes on modern AAA titles with Linux support. I could care less about <1 year old games or synthetic benchmarks tbh.
- tankenmate 11y agoThe versions of the drivers in SteamOS are well behind up to date stable, let alone testing. You can easily pull in one of the many PPAs that track the latest stable and/or testing kernel/MESA/DRM/DRI stacks (such as xorg-edgers, obiaf or others). If you are not happy with what is provided by stock SteamOS then your issue is with Valve's distribution not the current state of the drivers.
- Shorel 11y agoHow much of that difference is because of the driver and how much because of a bad port from the game developer? Remember all the console to PC ports with really bad performance. Now add the lack of a financial incentive for Linux games. To put this in perspective, there are more Windows XP users than Linux users in Steam stats.
