mm but when i uninstall it swrast even with the swrast_x86 then GLinfo dont work. Why if the new is better dont come with the official xD?
The two engines have different set of problems, so currently you need to switch between them depending on what you want to run. As the issues in the new swpipe get fixed, we can remove swrast. But for now we need to keep both, also for testing purposes.
