Sculpting on objects with more 100k polygons (dyntopo constant detail 50 px) lags blender, especially using Snake Hook brush and dragging freezes Blender.
For comparison - on Win10 I can handle 1.5m polygons with Snake Hook with similar performance.
I have Nvidia 396, Cuda and most likely other Nvidia stuff installed too. I tried Blender 2.77, 2.79 from archive, from synaptic, on steam and 2.8 as well, all of them have the same terrible performance.
Since I was moving from Win to Ubuntu, I used Win startup.blend file so I have most of in-blender optimizations activated, Cuda, backface culling included.
Is this a normal occurrence and I should stay on Win10 or is there something wrong with my Ubuntu/Blender?
Hi.
Could you check if your problem is similar to the one in this report? https://developer.blender.org/T54807
The point is that in that report it was suggested that the problem may be due to AMD CPU, but you have intel.
Can you share a sample .blend file at the point where the problem starts to occur in Linux?
In Linux, have you monitored the system RAM and Swap usage at the moment the problem start to occur?
If you are going to comment on that report, please you provide as much information as possible.
Here is a screenshot of my System Monitor resources when I tried using Snake Hook brush on the Dolphin.blend that was included in report.
I can say for sure that my problem is the same.
What should I include in my comment on the report? I can think of only my entire setup, confirmation that I have that problem as well and my screenshot, something else I can provide?
Maybe you should open a new report mentioning your hardware and the problem. Then in your report you point to the link to the other report where it has been suggested that the problem could be related to AMD, so it is clear that apparently you have similar problem but with Intel CPU. You try to make a good comparison between what happens between Windows and Linux in similar conditions.
You share there a .blend file where it works well in Windows but not in Linux, or you test it with the same Dolphin file of the other report, but you make sure that the problem does not happen in Windows with that file.
