I'm encountering intense semi random brush lag whenever I work on a 'large' canvas.
Basically, the way I like to paint involves a large amount of separate brush strokes made really quickly. This normally isn't a problem, but with larger documents severe lag comes into the mix.
If I were to rapidly place 10 strokes, the first would start with a quarter second delay, and the last brush stroke would get drawn about 2-3 seconds after I finish brushing.
The lag seems to appear and disappear semi randomly: Whenever I open up the file in question, it works great for a few seconds, but as soon as I cheer and tell my colleagues, it grinds to a halt within minutes
The same happens when I toggle options, install updates, allocate more ram, etc
It works either not at all or only for a couple of seconds.
The 'random' part of the problem kicks in when I sigh and get to work using laggy brush strokes. After a little while, it clears up randomly, and I get lagfree strokes for a short bit, before it dies off again.
The particular document I'm having trouble with is 4300x3400, 8bit RGB, and has about 30 layers
I've been researching this topic today for over 3 hours, and I've been trying a multitude of different settings, to no avail.
Here is a full list of what I've tried so far:
- on an empty new canvas (4000x4000) I get the same random results
- checked graphics card drivers
- updated windows
- allocated more ram to photoshop
- turned off my graphics processor
- turned openGL support from basic to advanced (and later back again)
- tried different brushes and brush spacings
- resizing the file in question to half size
- turning off clipping masks
- minimizing the layer palette
- exclude the photoshop folder from my virus scanner
- several tiny things I cant recall
I cannot consistently replicate the problem, as it seems to appear and disappear at random.
I first suspected it to be a video card problem, but turning off the graphics processor in 'performance' ruled that bit out..
I would greatly appreciate any help I get to resolve this issue, so that I can get back to work.
Thanks for reading
