Good Day All,

I have been experiencing an issue with Killing Floor on my new [2week old, Mid 2010 edition] MacBookPro 7,1 (13"):

• Intel Core 2 Duo 2.4GHz
• 4GB Memory
• NVIDIA GeForce 320M graphics - 256MB
• Snow Leopard (fully updated)
• Running on Mains

When ever the STEAM Overlay (default: SHIFT+TAB) is used [in game or main menu] the overlay is extremely slow and the mouse is overly sensitive. For example: if i try type a message to a friend, it takes around 5 seconds from when I enter the letter before it shows up on the screen.

This is fine, Im not really using the STEAM overlay for chatting in game... However.....

When I am in KF and I obtain an achievement, the entire time the achievement popup is displayed (Slide up, pause, slide down) my KF is lagging. As soon as the popup disappears its fine.

I have tested about 9 other Mac Games and none have this issue. I even opted in to the latest steam beta client... No luck.

I have checked the TripWire and Steam forums (http://forums.steampowered.com/forums/showthread.php?t=1657036), however I was unable to find this issue mentioned. Does anyone have a similar machine without this issue?

I attempted to:

1. Updated drivers (already the latest)
2. Reinstall STEAM and d/l KF
3. Defragged the drive and STEAM files for KF
4. Removed the .blob file
5. Disable Expose and Spaces
6. Stop all other background apps
7. Cold Start (shut down for 3 hours, boot on power)

I hope that this can be resolved, without "get a PC" or "use bootcamp"...
