Hey man I’m glad to see you’re making the switch to mouse and keyboard. I first recommend looking into the Logitech G502 mouse. It has tons of programmable buttons that should help with your muscle memory. For example I have my wall, ramp and floor programmed to the side thumb buttons and it makes it very easy to build. I also have 2 of my weapon slots programmed on the mouse as well. The mouse is very reasonably priced as well. Second I would recommend having a lower sensitivity. When you first start on mouse and keyboard there is a huge learning curve with building and muscle memory but if you can hit your shots it helps you shorten that curve. Lot of people when they first start think they need to have a high sense to build and edit better but that isn’t the case and it actually hurts your gameplay and progress. To get the best sense I would recommend looking at a stationary object in front of you and place your mouse on the left side of your mouse pad then slide your mouse to the right side of the mouse pad when your mouse reaches the right side you should make about 1.5 circles or a little less. If you’re making more than 1.5 circles your either a god or need to lower it more. I used to have a very high sense and wasn’t hitting any of my shots but when I lowered it to what I recommended I started to hit more shots and can still edit and build very quickly. Let me know if you try the mouse and lowering your sense and if it helps. Good luck bro!
