However, game runs just great with everything set to max (sprites, textures, light, smokes etc).
Sometimes drops with high de-zoom near lot of bots, accumulators discharges or other animated entities (to 40FPS), but otherwise it can keep 150FPS (with game.speed increased). (My Factory is not very big...)
There is just one setting causing issues - Video Memory Usage. When it's set to HIGH, strange lag peaks appears. Every (exactly) 3s
Fps counter drops from 60 to 55, then backs to 60, until next lag.
Even in new game, with nothing around.
So, despite option description (Higher setting => increased performance), performance on HIGH is worst than at MEDIUM or ALL.
As I am assuming now, Medium setting requires <somewhere below 1024> MB of vram, High <somewhere above 1024> MB of vram and All means 1024MB.
So, therefore, High is above my vram limit, and GPU loads additional data every 3s...
But it is not obvious, and I have played long time with lags or unnecessarly reduced quality because of this.
Is it possible to change this setting options to something like this (add predicted/calculated/predefined memory requirements for each setting):
LOW (vram: 512MB-640MB)
MEDIUM (vram: 768MB-900MB)
HIGH (vram: 1210MB-1366MB)
ALL (vram: 1024MB) <= You have so much.
