[LPTuto] Improve performance on weaker PCs

[Raddeck]

To improve performance on weaker PCs try these tricks:

Esc > Settings > slide both of the following settings all the way to the left:
1/ PP Quality (FPS Intensive)
2/ Shadow Quality

On weaker PCs, you can gain an extra 10-20 FPS just with these two settings turned off.
And even with them off, the game doesn't even look bad - it will just have that 'clean' look without all the fancy post process effects - some may even prefer this look.
