The Intel kernel module should load fine automatically on system boot. However, the modesetting driver can cause problems such as screen tearing and mouse jittering on XFCE, artifacts when switching virtual desktops in Chromium, and vsync jitter/video stutter in mpv. See, , Xorg#Installation, and modesetting(4). Note: Some ( Debian & Ubuntu, Fedora, KDE) recommend not installing the xf86-video-intel driver, and instead falling back on the modesetting driver for Gen4 and newer GPUs (GMA 3000 from 2006 and newer).


6.4 Font and screen corruption in GTK applications (missing glyphs after suspend/resume).6.2 Disable Vertical Synchronization (VSYNC).5.2 Hardware accelerated H.264 decoding on GMA 4500.4.3 Intel GVT-g graphics virtualization support.4.1 Framebuffer compression (enable_fbc).Most of the sites that want to draw comparisons I've looked at seemed a bit biased, or just made poor choices in how to implement testing using modern DX vs out dated OpenGL, single program, what not. The real problem is that there are a lot of politics involved (open source vs MS) in the discussion and to get to the heart of the matter an unbiased group would need to test every implementation of each API version(s), and a large group of programs, to give the rest of us a sense of what's really going on. As most are aware, Valve is outspoken about OpenGL performing better than DX. A publishers implementation of the API can have a huge impact one way or the other. The real pita is that performance comes down to a lot of competing factors, and such a general statement may not be advisable. Through a bit of google-foo research I would draw the conclusion it would be the same case for OpenGL vs DX9. Looking at the GFXBench results on a few different implementation of the Intel HD iGPU I would say OpenGL.
