Lagging viewports & Slow Performance | Fall Creators Update

Recommended Posts

Hi all

Grabbed myself a copy of 3DC a couple of weeks ago, have been loving it so far.  Last week I got the dreaded Win10 popup for the fall creators update - dismissed it with remind me tomorrow, and it installed itself anyway that evening on shutdown (the joy!)  Anyway it pretty much messed up my adobe CC installation - all psd's saved out were corrupt, so I decided to reformat my OS drive and start afresh (as I usually do every 6 months or so).

Installed 3D Coat again today, and the peformance seems to have taken a massive hit.  I'm running in DX Mode, but the viewports lag when rotating and panning, even with just a basic primitive.  Have tried toggling cuda on and off, and still the same.  PC Specs aren't amazing but wasnt a problem before the update - would have thought it would be better now after the refresh rather than worse!  Am running all the latest drivers for the below

Any ideas greatly appreciated!

 

  • Windows 10 Pro 64Bit (Fall Creators Update)
  • i7 6700k (OC'd to 4.5Ghz)
  • 16GB Corsair Vengeance 3200
  • Gigabyte Geforce 980 Ti Windforce
  • Samsung EVO 850 SSD for OS and 3D Coat installation

Do you get this lag in other 3d software as well?

If yes its a driver issue , had the same issue a couple times with win 10 updates , uninstalled , clean uninstall drivers and 3d coat , restart , re install , restart.

There's got to be some kind of driver issue going on. Doesn't lag on my end. Try doing a clean install of the latest video card drivers.

Thanks!  I only have Blender installed atm, but no lag whatsoever with that, neither on Battlefield 1.  I've uninstalled 3DCoat and just clean installing the latest driver 388.00 then will try again.

Problem solved!  (Mostly) :(  Issue remained after the driver update, if I pan, zoom or orbit slowly its fine, but any reasonable speed and the lag occurs. 

Really strange, wondered if it could be the 3dconnexion drivers for my space navigator, uninstalled those and now its fine!  Although not sure if it's now an issue at 3dcoats end on the 3d mouse or I should contact 3dConnexion?  My navigator wasn't plugged in at the time btw, so definatley seems to be those drivers with 3dcoat?

It sounds like it was those drivers. Good job on fixing it.

I think Don (AbnRanger) has a 3dConnexion or at least this is what i understand from his tutorials , navigation feels like it.

Thanks!  Managed to narrow it down further.  Reinstalled the 3dConnexion drivers, issue remains but ONLY when the navigator isn't plugged in, so hah typical!  Can live with it for now, but one for the next 3DCoat update hopefully!

I have built separate "3Dconnexion" navigator test. Please download and try this test:
http://www.3d-coat.com/~sergyi/Tests/3D-Coat-3Dconnexion-Test.zip
This is the engine of "3Dconnexion" input from "3D-Coat". It will show how "3Dconnexion" device effects on the FPS (plugged and unplugged). Please look at FPS. Please try both executables (DX - DirectX, and GL - OpenGL). Do you see any slowdown? For example, on my system under DX gives more than one thousand FPS and GL gives almost one thousand FPS (with plugged and unplugged "3Dconnexion SpaceNavigator", during navigation and without navigation).
 
Also I have compiled two special executable files of "3D-Coat 4.8.04" for Windows:
http://www.3d-coat.com/~sergyi/Executables/3D-Coat-4.8.04-NoSleepExecutables.zip
Overwrite existing executable files "3D-CoatDX64C.exe" and "3D-CoatGL64C.exe" (or rename them before extracting the archive). Using these executable files FPS should never be low (even if you do not move the mouse or tablet pen, please pay attention to this detail). Run them and select Voxel Sculpting > small sphere. On my system DX give almost 300 FPS (with plugged and unplugged "3Dconnexion SpaceNavigator", during navigation and without navigation).
 
Please contact me directly "support DOT linux AT 3dcoat DOT com".

Andrew pointed me at this thread, so I hope there's no issue in me posting here. I'm seeing severe performance issues with both 4.8.03 and 4.8.07 on the following system :

 

6700K

64 GB RAM

6 GB GTX 1060, current drivers via Geforce Experience

Win 10 Pro (Slow Ring Insider)

SSD storage throughout.

 

Using the example humanoid with voxel sculpting, the lag is over the order of a second or more between action and response. This is pretty much identical between GL and Direct X, maximized or small window application.

I don't have 3D Connexion drivers installed, but do have the device (physically disconnected, rarely used)

 

Using the navigator test build,


DirectX is reporting a constant 60 fps.

OpenGL is reporting a varying ~1500 fps

I have fresh installed on my old unused system (Core 2 Duo E8600 3.33GHz, 4GB RAM, GeForce 8800 GT 256MB) Windows 10 Home (64-bit) from Microsoft site and graphics driver from NVIDIA site. When "brushing" with size 20 on standard "Head" model "3D-Coat 4.8.07"  shows ~51 FPS under DX, and ~48 FPS under GL immediately applying brush strokes. The strange thing is that inside "Log.txt" on my system the driver is "nvd3dumx.dll" (which according to Google search is part of "NVIDIA Windows WDDM D3D driver"), but inside your log the driver is "nvldumd.dll" (which according to Google search is "NVIDIA driver loader").

Not sure what to say. The nVidia drivers from GeForce Experience are installed (388.71) and DirectX is being used by games, etc. as one might expect. For both OpenGL and DirectX, the experience is extremely laggy and I can't explain why that might be, either.

Have you updated your Wacom tablet driver? That, too, can be a source of INPUT lag. Has happened to others in your situation, before, and sure enough...updating it fixed the problem. Also, if you subdivided the mesh where it is 30mill polygons+ in voxel mode, it might have some impact. But, I think it is an issue with either your graphic card drivers or wacom driver. I'm leaning toward the latter because it seems to point to INPUT lag, rather than display lag.

No tablet was in use or installed on the system 

Ouch. You're using a mouse to sculpt with? That's a bit like trying to eat soup with fork. I'm kidding...but not really. :D

Can you try to uninstall the app and install the latest version for your OS?

My tablet died, so I'm making do for now. I've seen/heard of a lot of trouble being caused by Wacom drivers of late, so have been holding fire until the dust settles.

 

The slow down is the same for both 4.8.03 and 4.8.07, so I don't think it's installation-related.

I know you said the drivers aren't installed for the 3dconexxion but have you tried connecting it and seeing if the performance is the same?  For me the lag only occurs when the device isn't connected

No, I haven't tried that. I have discovered that the tablet is actually working - not sure what changed. So I've installed the Wacom drivers and will take it for a spin.

I don't know what, if anything, the developers need from me at this point to figure out why the software is running so slowly.

Hi, Sergyi, looking at your report, it seem you had a fresh installation of windows 10 and installed the windows update drivers for the video card and not got it from the nvidia web site directly.
Can you confirm that you downloaded and installed the driver from NVidia web site?

The lag, I saw in the video were refresh redraw update, like as 3D Coat requested an update to the rendering of the scene and something interfered (could be potentially a issue with the GeForce experience or Windows 10 game mode stuff). I doubt it could come from a driver tablet.

I'm working with the GL version here in Windows 10, but keep GeForce experience not opened. On Windows 10 they recently implemented in game mode the game bar with DVR screen recording. That may be interfering with 3D Coat. All of that stuff is off here.
