@kiwibacon Your setup is more than enough to play star citizen at highest settings. The current alpha has performance issues that stem from bugs, memory leaks, server-side issues and lack of optimization... since it's an alpha.
You may experience stuttering, framerate drops and occasional memory overloads, but those are not your system's fault. We are alpha testers... we may occasionally have fun in SC, but our main purpose is to point these things out and provide telemetry data so they can be fixed.
1. there is no uber setting and to be honest the graphics settings don't do much at all
2. as of now your fps are network bound so just throwing more hardware at it doesn't help
3. the current RAM usage is about 8 GB so as long as you have Chrome closed you're probably fine
4. 3.0.1 is the most unplayable patch we ever had so I'd suggest waiting 4 weeks 6 weeks for 3.1
