Hi all,
the last days I tried to get blender into working state on a 2nd gen Thinkpad X1
Yoga.
tl;dr
blender is stuttering and jerky on my X1 running an I7-8550U / UHD620 (4-core,
2/4Ghz) and FreeBSD, while it works like a charm on my Surface Go Pentium Gold
4415Y/HD615 (2-core, 1.6Ghz) with Ubuntu.
This is both on 12-STABLE and -CURRENT. It’s a bit better on -CURRENT, but still
horrible.
Is there any way to speed blender up on FreeBSD?

Long version:
I wanted to try out blenders Grease Pencil, up until now I only used blender for
video editing.
GP or rotating 3D-Scenes in blender 2.90 on 12-STABLE was abysmally slow and
crashed repeatedly after a few strokes with grease pencil or a few minutes work
in the 3D-view with:
The GPU reset did not work, machine hangs, reboot via ssh.
Recompiled blender, tried older version, all with the same result, although 2.8x
seemed a bit faster, but still slow & crashes.
Searched the web, found similar problems by others on Linux, suggested KMS
update.
So I switched to -CURRENT with drm-current-kmod (5.4 instead of 4.5)
Same GPU hang, but here the reset works. Performance *slightly* better, but
every hang takes about 2 sec, no way to work with this.
Updating X1 bios - now the error did not happen for quite some time.
But still, quite slow. Stuttering when rotating the default cube in simple solid
or wireframe mode. On a I7-8550U running full speed (hwpstate_intel with
epp=0), cpu freq between 2500 and 3900).
Installed mesa-devel:the GPU hang is back.
Recompiled blender to 2.91.0_2, mesa-devel, drm everything. No more GPU hang for
now, but still stuttering motions, Grease Pencil strokes hang back 1-2 seconds
from my stylus.
Then I tried my 1st gen Surface Go 8Gb running Ubuntu: Blender is blazing fast
for these simple tasks. Fluid rotation, allmost real time grease pencil:WTF?
This is an i7-8550U quad core running 2/4Ghz with an UHD620 GPU against a
Pentium Gold, and the Pentium wins hands down?
I would really *love* to get blender up even only to Pentium speed. Blender with
simple models in solid mode should *fly* on my X1, same with a few Grease Pencil
strokes…
Any ideas, help, suggestion?
Thanks, Mathias
