With modern computers we have a lot of memory (RAM). And with HD, 4k, 8k... you create projects that are bigger than in the past. This is normal
![Smile :)](./images/smilies/icon_smile.gif)
But with a higher framerate (more instances) and bigger image resolutions (more pixels), be aware that it takes more memory for TVPaint to deal with it.
So you should not use the 32-bits version of TVPaint anymore ! this version can actually only use 4 Gb of memory. As soon as the memory required to handle your project(s) exceeds this limit of 4 Gb of memory, TVPaint 32-bits will crash. This can happen at load, but also while you are working on a project.
Please stick to the 64-bits version. It's more reliable.
