Photoshop scratch has async I/O enabled

Another option suggested I disabled GL but the advanced interface did not have the open GL option visible in the same location as the guide.

I did not have brush lag until I started using the air brush. I did increase canvas size and make the file much larger but the lag did not happen until after I switched brush types. It is possible that I did not notice the lag until I switched.

mine is also not working, I have tried a lot of different things suggested on here and other places but it seems that it still lags and it messes up when i'm trying to draw and it has to load and I have to wait to see what I drew. Is there anything else that I could try to fix this problem?

Would you start a new thread please. Tell us:

Photoshop version?

Operating system?

If you are using a tablet and if yes, which one?

Does the lag happen with both mouse and tablet (if you are using tablet)?

What the image and brush size are in pixels, that cause the lag, and try to explain how bad it is.

Lastly open Photoshop and go Help > System Info > Copy and paste to this thread with Ctrl v.

Thanks

I'm going to necro this super old thread because it's the top result for "photoshop brush lag" in google. An artist I work with had a lot of brush lag when the GPU was enabled. He has recent drivers. He has a super fast computer, so it shouldn't be laggy. Disabling the GPU stuff helped a lot, but didn't solve the problem. He works in 4000x4000 pixel canvases. When he zooms in the problem is less pronounced.

Ultimately I found that some of his brushes were unaffected. I narrowed the affected brushes down to ones with the "Dual Brush" option enabled, and all of them had 1% spacing. Increasing the spacing on the Dual Brush setting removed the brush lag.

Hope other people find this useful! That much input delay is disgusting!

I'm having the same problem and came across this youtube video that seems to help (but doesnt solve the problem): Solution to Adobe Photoshop CC Brush Lag Bug - YouTube

In the brush preset, increase spacing to greater than 2% (say 11%) and that does help

How big is the canvas (in pixels horizontally x vertically)?

What mode and data depth (e.g., RGB, CMYK, grayscale; 8 bits/channel, 16 bits, etc.)?

How big is the brush in pixels?

What brush is selected?

You mentioned the airbrush option enabled. What are the other settings?

Ideally, a screenshot showing the whole desktop environment when you're brushing will be helpful.

Can you quantify the lag? As in, "I click in the upper-left corner of the image, then shift-click in the lower-right corner, and it takes the brush x.y seconds to stroke across the image." Be as accurate as you can; a 0.5 second lag is way different than a 5 second lag.

Be aware that very large brushes have to manipulate a huge number of pixels and can slow things down.

I didnt have airbrushing enabled. I was using the "airbrush." I think it was airbrush low density grainy at quite a large setting as I was working on blocking in a background color change. I believe in the area of 100 pixels. I also switched to one of the spatter brushes shortly after, similar in size. When I use the shift click option I approximate the lag from top left corner to bottom right corner is 4 seconds. It is quite a lot of lag. In photoshop CS5 my computer ran very large images without issue regardless of brush size. In fact I've done larger images by multiple times...several thousand pixels.
