Repeated GPU Timeout after drawing to render target

(Enduring Games)
Included Insights trace to show the memory spike in LLM followed by some pretty large time
cost frames in the timeline. (Link to insights trace in comments section)

1. Create a blank map.
2. Create a blueprin..
3. Add a function that has a Create And Assign Render Target at 4096x4096. Choose
any format but R8 can be a good test since this involves memory. Cache the render
target in a local variable.
4. Use this variable and place “Draw Material To Render Target” with “WorldGridMaterial”
as the material selection.
5. Enable “Call In Editor” for this function.
6. Place new BP in the world and hit the function call button in details panel and observe
the spike in vram usage followed by a lagging editor for some time.VRAM spike does
not reduce until editor close
