$ es2gears_wayland
EGL_VERSION = 1.4 (DRI2)
vertex shader info:
fragment shader info:
info:
597 frames in 5.0 seconds = 119.138 FPS
600 frames in 5.0 seconds = 119.880 FPS
598 frames in 5.0 seconds = 119.481 FPS
600 frames in 5.0 seconds = 119.952 FPS
600 frames in 5.0 seconds = 119.880 FPS
600 frames in 5.0 seconds = 119.880 FPS
