Minecraft Runs Slow With Open Source Radeon Drivers

When trying to run Minecraft with Radeon open source drivers I’m lucky to get 10 fps. When in Windows I get way more. What’s the issue with this? I’ve seen several threads on different forums asking this. S I know it’s not just me.

Many games have video settings. Did you try tweaking them and checking the results? Also, i assume that with proprietary you have better results?

I put my render distance on tiny and everything else on low settings, installed an FPS booster (optifine) and still am lucky to get 10 FPS. I have been told that for my video card (ATI Radeon Mobility X1400) the open source drivers are the best I’m going to get in Linux. Is there anyway to install the Windows videos drivers in Linux?
