[0.18.4] FPS drop

[Merssedes]

Started getting FPS drop.
On normal zoom everything is OK. When zoom out, i get drops.
2 pairs of sscreenshots (all requested debug info doesn't fit into window):
"good": default game zoom
"low": zoomed to factory map view
same zoom works OK if not rendering factory

Also (can't post related info though) I had drop to 10-40 FPS (position dependent) in multiplayer with normal zoom.

Turn off electric grid overlay in map view. (And possibly turret and roboport overlays also)

Turning off all overlays didn't change results
Well... 41-43 FPS no at the same zoom as posted one.
Also, it's not map-view related: same FPS i get if i zoom out from normal view to the same scale.
Disabling ALT-view gives about 50 FPS.

Can you reset graphics settings to default and restart the game?

Also you might want to update your graphics driver. The driver you have is over 3 years old.

Resetting graphics settings to default should fix it (I still recomend updating drivers, though)

Specifically: The main issue is that you have set max render threads to 1 ... so you get bad performance when there is lot of things to render now.
And, your GPU is improportinally more powerful than your CPU, so using Video memory usage set to All and Atlas size set to Largest possible should not be problem for the GPU, while gets lot of load off the CPU.

Resetting graphics settings (except fullscreen) mostly worked, but I still get drop (45 FPS) with maximum zoom out in normal view. At least it's playable with most zooms now
Thanx for info.

I'm kind of afraid of driver update because last time it caused my system to non-bootable state.
