Left 4 Dead Forum

Tried everything else and still not working or having a horrible framerate?

Install the Directx SDK and you should be good. Worked for me. But now I'm using Crossover Games 8 so It installs by itself when I create a bottle.

Download Here:
Directx SDK

To add on to what Noah said ..( didnt edit ..in due respect to what Noah said )

You could try launch options like

-novid

or even try toggling GlSl on mac..

Further more you could lower your screen resoultion when you play...remember the higher resolution the slower it gets..
use options like -h x -w x where x is the variable and h and w is height and width respectively (sorry was doing Additional maths before writing this post)

use launch options like -sw for windowed mode

Well..Wine and Crossover arent really perfect science ..but they are good effort.
Give them your time and patience and we , together , might just make your games work :)

yea...so feel free to post your L4d problems and rants 😀

Mind explaining how to do these? Its all greek to me.

Ignore the suggestion about "-dxlevel 80". It doesn't work for Left4Dead.

For "-novid", you can add that to the launch options for the game. In the Steam GUI, select Left4Dead and click the Properties button. In the Properties dialog, click Set Launch Options. Type "-novid" there (without the quotes). Close the launch options dialog and the Properties dialog. Now when you launch Left4Dead, it will skip the Valve logo video and the Left4Dead intro video.

The GLSL thing I explained in the other thread.
