All over the years I have always wondered why my Compiz animations on Gnome 2 are not as smooth as on my old Laptop running with Intel GMA 965. Maybe this is related to low frame rates. When I run glxgears (I know, it's no benchmark test) I get only values about 300 frames in 5 seconds:
$ glxgears Running synchronized to the vertical refresh. The framerate should be approximately the same as the monitor refresh rate. 302 frames in 5.0 seconds = 60.391 FPS 300 frames in 5.0 seconds = 59.919 FPS 300 frames in 5.0 seconds = 59.921 FPS 300 frames in 5.0 seconds = 59.921 FPS 300 frames in 5.0 seconds = 59.921 FPS
The text says that this frame rates are correct, but I can't believe that. This can't be normal, because I found forum entries with frame rates about 20000 or more. I think that my Nvidia GTS 250 can do this much better. Moreover Software Rendering is disabled, so that means that hardware rendering actually works:
$ glxinfo | grep render direct rendering: Yes OpenGL renderer string: GeForce GTS 250/PCIe/SSE2 GL_NV_conditional_render, GL_NV_copy_depth_to_color, GL_NV_copy_image, GL_NV_path_rendering, GL_NV_pixel_data_range, GL_NV_point_sprite, GL_NVX_conditional_render, GL_NVX_gpu_memory_info, GL_OES_depth24, GL_OES_fbo_render_mipmap, GL_OES_get_program_binary, GL_OES_mapbuffer,
Can anybody explain to me why a frame rate of 300 should be normal or maybe anything else is not correct?
