I just installed a fresh Fedora 11. I am running the NVIDIA driver (Twinview mode, not Xinerama), and an application that worked in the past that uses graphics (draws circles, arrows) now is unusable. When trying to interact with the graphics (drag, etc), the Java task shoots up to 60-90%. The larger I make the window (regardless of the same amount of graphics), the slower Java + xorg is. I went so far as to swap video cards without change (from Geforce 7 to Geforce 8 series). All this stuff worked fairly snappy under Fedora 10 under VMware. For Fedora 11, I have installed natively, and the native environment is dual headed. Does anyone have any pointers on where to look? I can run the glxgears program and get 15000fps or so.
Adding '-Dsun.java2d.opengl=True' results in snappy performance. Apparently since Java 5 (1.5) OpenGL acceleration is turned off by default.
