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: Jan 4 23:04:17 Danton kernel: drmn0: GPU HANG: ecode 9:1:0x87f99eb9, in blender [100824], hang on rcs0 Jan 4 23:04:17 Danton kernel: drmn0: Resetting rcs0 for hang on rcs0 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?
