The Current Intel "Iris" Gallium3D OpenGL Performance Against i965 Mesa, Windows 10 OpenGL

This is somewhat surprising. On my igp 620UHD based notebook, Talos principle ran soooo much better on Linux than on windows. And The Witcher 3 failed to run, whereas I can play it through Proton.
Seems that the Intel Windows drivers are not quite as bad as I thought…

"as bad" or 'as good' as you thought? 😕

Intel Windows drivers are not quite as bad

On windows, for some games to work you need to spoof gpu name as geforce/radeon instead of intel. Chances are, dxvk does that.

Typo:

though the Iris vs. i965 performance was simnlar.

Windows for light/single workloads and Linux for heavy/many workloads...

Phoronix: The Current Intel "Iris" Gallium3D OpenGL Performance Against i965 Mesa, Windows 10 OpenGL

It's been quite fascinating to watch the development of the Intel Iris Gallium3D driver that has now been in development by their open-source team for more than one year while back in February is where this currently experimental driver was merged into Mesa. It's been over one month since last looking at the Intel Iris Gallium3D performance relative to Intel's default "i965" Mesa OpenGL driver. Here are fresh benchmarks looking not only at their current and next-gen OpenGL Linux driver options but also how that performance compares to their current Windows 10 OpenGL driver.
