Ram Problem on Big Maps

[Darkneblade_TR]

I have a problem about big maps in warframe

whenever i get into sabotage mission on void my fps is a below 10 fps or any big maps thats why i have inaros self healing tank so i dont need other people (850 mb ram uses if 4 people on my team if im 1 it uses 700 mb around ) and i need to run from steam which steam uses ram too which is my big problem i cant run from directory it asks me directory (?) 

the other maps fine i uses 650 mb ram mostly when alone when not alone it 700 around again which still fps drop but not like void sabotage 

I have 2 gb ram 

I cant buy a new ram because in here it ridiculously expensive any help appreciated

ram ist that expensive tbh even some of the corsair stuff is reasonably priced, another possible fix could be lowering your textures as the minimum requirement  for warframe is 2gb of ram.

i already lowered to minimum 1024 x 768 everything is minimum etc i dont mind 10 fps but 1 fps is too low when running out ram
