99% of the time low FPS in Counter Strike 2 is caused by setting your graphics settings too high. While everyone wants to play with the best graphics settings in the game, Counter Strike 2 requires a significantly more powerful set-up to run at the highest quality settings than Counter Strike: Global Offensive.

30–50 FPS—it's not too bad, but it could certainly be better. 50–70 FPS—at this level, your skills generally have no technical obstacles to shine. Most CS2 players are happy with 60 FPS. 70–120 FPS—you need a nice, powerful computer and a good gaming monitor to support this number.

By double-tapping Q, you will swap between your last two used weapons. Similarly, pressing keys 3 and then 1 quickly would have the same effect, though that requires more of an effort.

Boot up CS:GO and load into the main menu. If you got into the CS2 beta test, you'll see a popup telling you so (or else a notification in your left-hand main menu bar with a message about the beta). Just click “Enroll” on the popup, and you're good to go! You may need to restart CS:GO to play the beta.
