Troubleshooting: Crashing after Gigapixel AI v4.0.0 update - GPU Usage & Performance

Our latest version of Gigapixel AI includes new and updated processing models that give v4.0.0 a more responsive and flexible application. Due to this, our minimum requirements for Gigapixel AI calls for 16 GB of RAM, or an allocation of 8 GB of RAM and 8 GB of VRAM.

For some users, this increase in program strength can significantly impact performance on your machine. To account for this, Topaz Labs has built in three different GPU usage modes that allow Gigapixel to better work with your system to get high quality results.

If your Gigapixel 4.0.0 is crashing or is very slow, here are a few things you can do:

Set your GPU usage to LOW

The advanced AI features of Gigapixel AI demand a lot of memory from your GPU. If you don't have enough VRAM, this can cause Gigapixel to crash. By default, your GPU usage will be set to medium. If your application is crashing, your system likely doesn't have enough VRAM.

1. Open your preferences...


2. Set "Allowed graphics memory consumption" to "Low"


Make sure all other applications are closed

Because Gigapixel AI requires a great deal of resources from your computer, other applications, such as Photoshop and Lightroom, may compete for those same resources and cause the program to crash. To get the best results from Gigapixel AI, keep other applications closed until you have finished processing your images.

Roll back to the previous version of Gigapixel AI

If you are still having trouble using Gigapixel AI, rolling back to the previous version of Gigapixel AI may be the best option until your operating environment is suitable for the application.

You can download and install the previous version of Gigapixel AI for Mac and Windows using the following links:

What do I need to get Gigapixel AI working?

If you think it might be time to upgrade your system, here's what we recommend:

1. Install more memory (RAM)

This is your best option. Random-access memory is relatively cheap these days and is a crucial component in your computer's overall performance. Our recommended RAM spec is 16GB. However, allocating 8 GB of RAM and 8 GB VRAM also meets recommended performance specification. For more information and to see if this is the right option for you, check out sites like

2. Configure More Virtual RAM:

If installing more RAM is not an option at this time, configuring your machine to allocate more space for virtual memory (VRAM) can help alleviate performance issues. The result won't be as great as installing more physical RAM, however, so may not have a significant impact on your experience.
