OpenGL Performance

[RichardDyson]

I recently gave 5.9 a spin. I still have the problem that anything involving OpenGL acceleration runs at a horrible pace. Intel HD4000 - Ivy Bridge.

I can confirm that the Intel driver is functional, not running vesa and that the sysctl variable for the aperture is set to 2 like it says in the instructions.

Is there any solution to this problem, or is it just the way it is?

I don't see a prior report.

Please post a dmesg and the contents of Xorg.0.log.

Enabling the xf86(4) aperture (using a non-zero value) is not needed if drm(4) is available. And, the aperture driver doesn't affect performance. If it is needed and not enabled, X doesn't function.

Forgive me for this. It was too much effort to get the logs off the machine. It did say that direct rendering was disabled due to VGA arbitration.

Plug in a USB stick to copy the logs and the whole machine freezes up solid, just like 3 years ago.

So I'm just going to concede on this one - atleast for now. FreeBSD still does the job.

From the 6.0 Changelog:

In intel(4), fix an undefined symbol crash when opting into uxa.
In sdhc(4) and sdmmc(4):
Implement DMA support (only ADMA2 is supported). There is a remaining issue with simultaneous use of eMMC and external SD card on (some) Intel Bay Trail hardware.
Enable the ADMA error interrupt.
Enable high speed timing for bus clock frequencies over 26MHz and advertise support for it.

The 6.0 release date is September 1, 2016. Hopefully your issues have been addressed.
