A year ago I reported a serious bug in SU 16 OpenGL Preferences; see:
"Serious Bug in Sketchup 16 Preferences OpenGL Settings"
But I was able to find a workaround.
This led to the changes in the OpenGL Preferences now in SU17 where SU tries to find the best settings.
THIS HAS FAILED BIG TIME at least on my Graphics card. But now I’m prevented from setting the optimal choice: No work around. SU 17 is therefore MUCH slower that SU 16. Its like I’m not using hardware acceleration at all. Since my Su 16 license expires 30 days after downloading SU 17 this is big trouble. Someone tel me if there is a fix for this???
Here are the dialogs on SU 16 and SU 17 respectively. Notice that the Pixel format is quite different.
