Gavin Scott (Zoot) updated the task description for T60379: Cycles preview lockup / memory allocation loop while changing adaptive displacement parameters..

Gavin Scott (Zoot) added a comment to T60379: Cycles preview lockup / memory allocation loop while changing adaptive displacement parameters..

I've been experimenting with adaptive-displacement some more today, and Cycles Preview rendering with Adaptive Displacement seems unprepared to deal with anything changing in terms of input or settings. It does not seem to know when it needs to actually calculate the adaptive displacement and even when it does, it usually fails to recalculate it if things change, which leads to an assortment of problems.

Gavin Scott (Zoot) added a comment to T60336: UI refresh rate - Bug or feature?.

"Round" frame rates like that in other applications/games are often the result of vertical sync. I don't believe Blender used to specify whether vsync should be on but I don't know for sure that didn't change in 2.80/Eevee. You might experiment with your Nvidia Control Panel settings and try forcing vsync off for Blender and see if that has any effect on what you're seeing.

Gavin Scott (Zoot) added a comment to T59833: Poor performance switching between Object/Edit modes and using Undo when using subsurface modifier.

I believe you're seeing the result of the switch to OpenSubdiv that happened around then. The current implementation lacks the CPU and GPU acceleration options that existed in 2.79, and is generally at least 5x slower than the old Blender subdiv code (it can also be substantially worse) which had been in use in 2.80 prior to the switch-over that happened just before Beta.

I believe current Eevee only supports camera motion blur and does not yet support object motion blur, which looks to me to be what your scene would require.

Gavin Scott (Zoot) added a comment to T59802: Preferences window opening behind main window when in fullscreen mode.

If you go to the folder where your 2.80 is installed, inside there is a 2.80 folder. If you go inside that and make a new "Config" folder (without the quotes) then that version of Blender will keep its configuration files there locally rather than using existing system-wide preferences. When you then start up Blender it will have a completely clean default config (it should start out asking for your left/right selection preference etc. on the splash screen).

Any other video devices in the system? Other video cards or Intel integrated graphics say? If so are you sure Blender is running on the 1070?

Gavin Scott (Zoot) added a comment to T59798: View port pixel error.

I would suggest downloading the latest 2.80 from https://builder.blender.org/download/ and after you extract it, go into the extracted folder and inside the 2.80 directory, create a directory named "Config" (without the quotes). Then start up the blender executable in the extracted folder. This will give you a clean version of the latest 2.80 build with fresh default configuration (stored locally in the 2.80/Config directory).

Just opening the scene and hitting F12 results in an unresponsive Blender here (Windows 10, Nvidia 6GB 1060, current 2.80) with extremely high GPU usage that has to be killed from the task manager.

Can you pack the textures into the blend file or provide them in a zip? Without the texture files I get a plain purple cube. Throwing a random image in place of the missing files does not produce anything that looks like an issue.

I'm also not seeing anything in the Windows build either. In the Render workspace, the Historgram is always showing a spike at around 27% (even before doing a render) and it never changes and none of the other scopes show anything.

What about printing out the vendor, renderer, and version variables when this option is specified? That way if it does fix a problem for someone you would already have at hand the information needed to update Blender.

Duplicated crash here (self-build current 2.8, Windows 10, Nvidia 1060) as described on the first try, but after a few more tries it seems to fail only around 60% of the time and otherwise starts rendering fine.

Just a note that it works great as long as you click and your drag motion hits another tab before leaving the tab area. If you click and (for example in the vertical properties tabs) move directly left or right out of the tab column then it fails to work.

The number of pixels in the frame that are actually covered by the previewed material seems a bit small. What about having an additional button like [2X] or [Zoom] that would toggle the preview to show the middle 1/4 of the frame at 2x resolution (or maybe 3x would work better) to give a close-up view to see things more clearly? I think I'd use that a lot.
