Made by the same guy who made FOV CHANGER for MW3 and MW2.
Released 10NOV2013

Anyone who's played the game already knows how poorly the game is optimized for the PC. Here are some fixes really helped out my FPS drops and general overall stability of the game.

- Disable steam overlay if used with DXTORY or FRAPS. Or uninstall DXTORY or FRAPS altogether. Apparently there's a huge problem between the capture programs and GHOSTS.
- Go to task manager > "right-click" COD:GHOSTS > set PRIORITY to NORMAL (not high). This is causing huge memory leaks.
- Make sure your NVIDIA or AMD drivers are updated!
- When setting graphical settings, never set things to "AUTO". The game will try to optimize/compensate to 60FPS (kind of like shitty V-SYNC) and will cause lag.
- Disable steam overlay by going to Settings > IN-GAME > UNCHECK "Enable Steam Community In-Game" (Only do this if you're having trouble. If you uninstall DXTORY and/or FRAPS, you should be fine)

Here are my settings:
Screen refresh: 60HZ
Aspect ratio: 16:9 WIDE (again, don't put this on auto)
Image quality: EXTRA
Anistropic filtering: NORMAL
Textures are on the lowest settings
Motion blur/Depth of field: off
Terrain detail: off
Antialiasing: 4X MSAA

This should provide some quick fixes until official patches are released. It's made a huge difference in my gameplay, since I don't have to overcompensate for graphical disadvantages.

Hope this helps!

It goes without saying, don't play against your friends! 'Cause I will boot you. If there's room, we will send you an invite after the game!

You have been warned...

I'll eat your face.

You'll probably hear us saying this a lot. If you don't understand why this is important, I'll happily walk you through a map for TDM or DOM. Let me know, and I'll jump on real quick.

It's simple and it helps control the flow of the game. Also, watch your KDR go up...
