GPU load

[Boldtaar]

My GPU is working hard fan blowing like crazy. CPU fan in blowing harder after 30 min of LOS map design in FG than 12h marton FPS gaming.

GPU load jumps between 15% and 99% every few sec.
Radeon RX 570

This is not very helpful information. Maybe it is worth mentioning the computer details and also what kind of maps (size) and complexity of the LOS are you doing. Things can dramatically vary between one map and another. Including the computer specs.
Maybe attach the campaign.

The pixel resolution of the image, along with the number of LoS points, lights, FX and more on the map can have larger/smaller impacts on performance.

We'd need to get more information and/or a sample campaign with the images in question.

I've found using the vsync command documented on the wiki makes a huge different in gpu/cpu usage: https://fantasygroundsunity.atlassian.net/wiki/spaces/FGCP/pages/1638006786/Reducing+GPU+Usage
