Hey folks,
Quick question regarding hardware optimization. I recently upgraded my PC to 32GB of RAM and an NVMe SSD, but I’m still noticing some stuttering and brush lag when working on massive digital painting canvases (around 6000x6000px with dozens of layers).
I’ve looked into the Preferences under System Resources, but I’m a bit confused about how high I should safely set the "Resource Cache" (Tile Cache). Is it safe to allocate around 70-80% of my total RAM to it, or will that starve my OS and cause system instability?
Also, does GIMP actually utilize GPU acceleration effectively through OpenCL on modern setups, or am I better off leaving that toggle unchecked? Any advice on making GIMP run as buttery smooth as possible would be greatly appreciated!

opening the image leads to funny action - cannot see any thing but a black box

what is aimed: i want to work on a output of a scatterplot.  This should have a transparent background. but duhhh - i am not able to open it i n Gimp.

what goes wrong here ? 

look forward to hear from you 

   

It is fantastic that GIMP exists. This article provides a nice perspective on graphics software.

            Hello,

I am using GIMP on Windows and an XP-Pen tablet.

The tablet works normally in Microsoft Paint and I can draw without any problem.

In GIMP, the pen is detected and appears under Input Devices. The cursor moves normally, but when I try to paint on the canvas nothing is drawn.

What I have already checked:

Brush tool selected
Opacity 100%
Visible layer selected
Foreground color set to red
Tablet works correctly in Paint
GIMP detects the XP-Pen stylus

When I touch the canvas, I only see a strange cursor/icon near the crosshair, but no brush stroke appears.

Could this be related to Input Devices, Windows Ink, or a tablet configuration issue?


Screenshots attached.

Thank you.

I am using GIMP on Windows if that matters in Single Window Mode.

It looks like I did something, unknown to me, which has caused the tool options to stop being displayed in the frame on the left side of the window.  It looks like they now appear in the top of the frame on the right side which, for me, normally displays a histogram.  I think the setup I prefer is the standard default (out-of-the-box so to speak.

I'd be grateful if someone could explain how to restore GIMP to its' prior state.

Software-update: Affinity 3.2.2

I am new to using plugins and have read about LayerFX, but cannot find where to download for GIMP 3.2. I am using Windows 11. I did locate it as part of PGEI but, as I have no idea what PGEI is, I avoided it. Web searches have only shown me older versions. Thanks for any tips on this.

I'm opening multiple uncompressed TIFF files and exporting them someplace else after editing.
I have to manually select LZW compression from the dropdown every time.
Is it possible to set it as a default, even when exporting an uncompressed file?


Thanks in advance.

Hi! Is anyone here doing comic book coloring in GIMP? I'm doing just fine with flatting, but I wanted to color a comic book page from start to finish. I cant find any decent tutorials on YouTube, but I found this: https://www.youtube.com/watch?v=J_uNnawaBmE

The problem? It's for Photoshop, and I am having difficult time translating this workflow to GIMP. Does anyone here can help?
