I have had a read about on the internet and I have found and put together some ideas for options and tweaks that can seriously help fps
-Have an Anti-Aliasing tweak, have 4 options: Very high, high, low, Off
-Have a render distance slider, so people with bad GPU’s can get around 20-30 fps (Its helped in most games )
-Maybe adjust the render quality of the tree leaves and grass as they have caused a lot of fps issues lately
-Have an option either in console or on options menu to turn of shadows completely, maybe shadows off
-Maybe make the render quality slider have more effect on the world
I hope you can have time to adjust these things if you read it because lots of people are not playing because they get really bad fps like 10-15 :(.
Its a shame because rust has a lot of potential
