Hi everyone! So i changed system recently and now i’m studying on an intel i7 CPU, NVIDIA GeForce GTX 1050, 16 GB RAM. I tried to paint in Texture paint mode, but the strokes are pretty laggy!
Can’t help you on texture paint ,but I noticed it was really lagging in sculpt mode(2.79rc2). I tried blender 2.78 and I didn’t have the lag.
no problem with sculpting, only painting textures, tried older version, same problem…
Anyone can help? I believe the problem is with windows 10, but i really don’t know how could it be possible…i found out sometime in the UI i get lagging menus either…
Did you turn off all the Windows 10 touch stuff? Many tutorials online to fix Windows 10 Wacom lag/pressure/touch issues.
i don’t have any “touch” setting to turn off…i still have the problem no matter how big is the texture size…
Hi.
To rule out hardware problems, you could test a Linux distro in Live mode. You boot in Live mode, then you install Blender from distro repositories. Or you download blender tar.bz2 official file, extract it to a new folder, and you run there “blender” file (double click).
HI! thanks for your reply! I simply solved it by changing the Window Draw Method to “full”. Hope it can help!
Always close and re-open Blender after tweaking the system user preference!
Hi.
“Full” is not the best method. Have you tried with Triple Buffer for example?

i tried it, didn’t work. i get rid of texture paint lag only in “full” mode.
I m using windows 8.1 with 2.79 and the lag is horrendous in the 3d view but when I paint in texture paint mode in the image editor it upates the 3D view port in realtime ??? I have tried all draw methods but no success so far, I will download some older builds to try out
I tried out some earlier builds and new video drivers (nvidia card 660ti) not much of a change so looks like I need to try and back trace the issue to see if I can find a cause of the problem…
I tried out different builds,New Drivers,Fresh OS install via HD image
The objects in my scene painted with no lag when I imported them via append so something I missed…
I found out the cause via more button clicks
I had set CPU thread count to fixed and maxed it out for some reason, when set back to auto
ie 8 threads it works a treat 
Hopefully this helps out other blender users

hi, I had the same problem. I had the cpu thread count on fixed and set to 1024. I thought that setting was only for rendering. I am confused about what it does now. Anyway setting the cpu thread count to auto made my texture paint super fast again. Thanks Jonathon!
Yeah I thought it was the thread count for rendering as well… good to hear the info was of use
