Excessive VRAM memory usage
Issue
I have notified Interactive Map becomes slow after a short period of time and use lot of VRAM.
Replication
- Open a save with a big factory (no need of a mega factory)
- Zoom in and out on the map for one minute on crowded areas.
Actual Result
VRAM usage goes really high (8-10 GB) quickly. The map freeze from time to time, especially after tab switching.
This is with very few tabs and programs running in the background.
I have 32 GB of RAM and a 1080 TI so available memory should not be issue.
Expected Result
VRAM usage stay reasonable, no freezes (eg: Google Maps stays below 1 GB).
Yeah but Google maps doesn't draw thousands of polygon, I'm doing a whole lot of optimisation every now and then, but not sure much can be done.
Have you tried lowering the polygon details under options?
I have tried low detail mode but it does not really help (I did a full refresh and make sure it's applied correctly (eg: buildings now looks like a dummy square). GPU usage still reach 10GB after several zoom in / out. I understand it does lot of rendering calls but I don't think it should use that much memory. Would there be a possibility there is some memory leak ? (eg: non disposed objects / buffers)
Can you reproduce it at your side ?
Just tested some Zoom In and Out, and the memory was moving back and forth as expected, did not notice any excessive usage? Can I get your save to run more specific tests?
