Greetings. Problem fixed.
In the relevant config.txt file (if you run game.bat change config.txt, if you run 'potato.bat' change 'potato.txt') in the media folder change this setting:
lowmemory=0
to
lowmemory=1
That halves the texture size for all 3d models and frees up about 1GB of VRAM for no noticeable loss in visual quality.
On my PC my VRAM usage for the entire system (OS + Game) drops from 3.7GB to about 2.7GB
Main system memory for the game runs at about 1.5GB.
Reducing screen resolution to 1920x1080 or less will also reduce VRAM usage.
