Basically what I'm looking to do is set up an OS this one happens to be the one I chose because it has the best community and less scary windows-centered security concerns but I'm having a few noticeable issues from the gate.

1.) Frame Drops - I understand frames wont be the same, but I'd at least like to get around the 200 area

2.) Mouse options - I need to figure out either how to install my mouse software or how to easily change the mouse dpi AND TURNING OFF MOUSE ACCEL ALL TOGETHER

3.) Nvidia Settings - On windows I usually go in the nvidia control panel and play with the digital vibrance, gamma, and some of the aliasing settings and other little things as well as set my monitor to 144hz manually. All of which things I don't know how to do on Ubuntu and would like to learn.

If you could teach me anything at all I would sincerely appreciate it, because I really want to learn I just don't know where to go for these types of questions other than forums, and so far had not had much luck. Thanks again! :)
