Terraria FPS Guide (3 STEPS)
This is for the people that struggle to play.



1) The fundamental changes.

Turn Frameskipping OFF! <<< This helps a lot.
Turn down the ''Multicore Lighting'' from 4 to 2 or 1.
Change quality to low.
Go to effects and switch ''waves'' quality to low.

2) Making natural effects.
-----------------------------------------------------------------------------------------------------------------------------
Let's change the launch options of the game.

Go to your steam library > Right click Terraria > Properties > Set launch options < and follow that by pasting this next line:
-high -malloc=system -USEALLAVAILABLECORES -nomansky +mat_antialias 0

It's going to give Terraria a bit more power to run.
If your pc is not having trouble running terraria you can remove the -nomansky and the +mat_antialias 0.
-----------------------------------------------------------------------------------------------------------------------------
3) If all that is done and the game somehow stills, try the following:

Go to settings (on terraria) > video > resolution > and keep lowering your resolution and testing how much fps you got.

Have fun guys! :)
