Description
Ideas for enhancing performance:
- The VP the user is actively working in within Blender should get full resolution / sync priority. Additional viewports would be updated slightly less (I'm talking 60 FPS -> 30 FPS, so still reasonable speeds) while also getting a lower resolution texture to reduce copy effort (e.g. 75% or 50% resolution)
- Try packing as BGRA/RGBA in transit. Some GL articles claim that there's a performance boost this way (since the driver doesn't need to do any conversions during upload) - but we gain ~2 MB/frame overhead for all copy ops between apps

Research direction
Start by inspecting the viewport synchronization and texture upload paths involved in Blender and Unity rendering; no files or tests are named in the issue. Define and measure active-viewport priority, reduced update rates and resolutions for additional viewports, then evaluate BGRA/RGBA transfer performance before considering the work done.
