blender v3 experimental: texturepaint viewport lag what are fastest settings?
blender has a really bad lag texturpainting,
so far tried
undo set 5,…but 5 undos on atexture paint is shit for mistakes
texture size 2048…really too small to be viable…except concept art
single map to material output
collapsing all modifiers…esp mulirez… but really is poly count above 10k poly lags)…tried disable all
brush spacing above 10 (above 10 slightly faster but spotty brush)
brush stroke input samples min 1 def (4 samples much slower)
eevee min viewport samples (no difference)
prefs: image display default auto set try set to glsl(maybe slightly faster negligible)
cycles threads auto detect and try thread 1(is slower)
tried brushes in same folder still lag
tried scene lights and world still lag
try single image mode at top of texture slot…still LAG(negligible effect)
try ortho view LAG(marginally faster)
changing the stroke from Space to Airbrush under Brush settings to Rate .01( no effect)
only one object in viewport
zooming in
obviously bigger brush far worse
if model 8k poly above settings is just about usable except very big brushes,
have 6gb vram cuda…system 16gb ram
500k poly will close to FREEZE UNUSABLE
IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII
THE ONLY SETTING THAT WORKED FOR ME WAS TO TURN OFF OCCLUDE IN TEXTURE PAINT
spoils what is quite a good free program
makes it virtually unusable for texture painting
done most of this

In order to avoid painting faces that are behind the ones you’re painting, Texture paint uses “Occlude”, which does an obscene amount of depth calculations if you have occluding faces under the brush. It can be very slow, freezing Blender completely even for minutes.
