Hi, i have just that same problem. When i play without mods everything is ok, v 0.11.8.
Today i install some mods:
DyTech-Automation_1.3.2
DyTech-Core_0.13.3
DyTech-Energy_1.5.0
DyTech-Inserters_1.2.0
DyTech-Modules_1.3.0
DyTech-Transportation_1.3.0
RailTanker_0.0.7
and now when i try to start new map or something, ive got this error:
http://scr.hu/1vv8/k3pwi problem... Sometimes (1920x1080)...
When i delete Rail Tanker i can play normaly with DyTech, but sometimes i get crash.
I have Radeon R9 270 [2GB VRAM] , 8GB RAM, 4 core CPU so my PC isnt bad. So how i can have low video ram to load some texture in the BEGGINING of the game if i can (theoretically ofcourse) enough VRAM to load Factorio [~200MB] 10 times ;d
btw. sorry for my very bad english.
I can understand memory leaks etc. when i play hours. But how i cant load some texture even before map started?

this texture have 2000MB or what ? ;d
Sure when i put graphics on LOW it load map and works (dont test how long), but thats not the point and not the solution for me...
