Environment Details

• Foundry VTT Version: 0.7.3
• Operating System: Windows 10
• How Are You Using Foundry: Native Application (Electron), but bug and on Chrome
• Which Game System: tested with pathfinder 2e and dnd5e

Issue Description

FPS drops when the camera approaches with the mouse wheel, if there are huge light sources on the scene (the light shown in the screenshots with parameters 40/80 and an angle of 60). The fall in FPS occurs sharply when approaching a certain percentage. The fall occurs the same with a large number of light sources

Example scene (avr FPS 45) Huge light source Before scaling view After scaling view After scaling view with disabled huge light

Thanks for the report, this is a major known issue that I'm currently actively working on. I hope to have a resolution posted in Discord soon.
