Bug ID: 106053 Summary: Drawing at screen boundary is very slow. Product: Mesa Version: unspecified Hardware: All OS: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r300 Assignee: dri-devel@lists.freedesktop.org Reporter: cosiekvfj@o2.pl QA Contact: dri-devel@lists.freedesktop.org CC: alexdeucher@gmail.com, emil.l.velikov@gmail.com, Hi-Angel@yandex.ru, lemody@gmail.com, madbiologist2016@outlook.com, maraeo@gmail.com, mark.a.janes@intel.com, michel@daenzer.net, nhaehnle@gmail.com, notasas@gmail.com
Created attachment 138844 --> https://bugs.freedesktop.org/attachment.cgi?id=138844&action=edit bitmap for testing
When a partially visible sprites are drawn to the screen, fps drops really badly.
code tested: https://gist.github.com/vfjpl/bd442e34036547e4ccb05200762fa274
fully visible = 73.8 fps fully invisible = 394 fps partially visible = 5.75 fps
The same situation is happening on Allegro library. I don't know enough OpenGL to test it directly.
I can provide more test results. Just ask me to do it.
Extended renderer info (GLX_MESA_query_renderer): Vendor: X.Org R300 Project (0x1002) Device: ATI RC410 (0x5a62) Version: 17.3.7 Accelerated: yes Video memory: 128MB Unified memory: no Preferred profile: compat (0x2) Max core profile version: 0.0 Max compat profile version: 2.1 Max GLES1 profile version: 1.1 Max GLES[23] profile version: 2.0
And small question. Why Max core profile shows 0.0? Should I open another bug-report?
