You can try NVinject.

The process:
1. Get NVinject
2. Backup your extensions
3. Remove any existing graphics drivers
4. Install NVinject
5. Reboot

1. You can go to http://nvinject.free.fr and check the download section. Here is a direct link http://nvinject.free.fr/files/Latest_NVinject.0.2.1.zip
Extract NVinject.kext to your desktop (It is important that it is on your desktop as the following commands will require)

2. Backup your extensions folder1. Give yourself root privileges so that you can modify files.
sudo -s2. Make a backup copy of your kexts. First we will make a directory called "backup" in our root directory to store them. Open Terminal and type:
mkdir /backup3. Change directories to /System/Library This will shorten some of the commands we have to type in.
cd /System/Library4. Copy your kexts to the new "backup" folder.
cp -r Extensions/ /backup/3. Remove any existing graphics drivers. Press enter after each line.rm -Rf Extensions/natit.kext
rm -Rf Extensions/titan.kext
rm -Rf Extensions/NVinject.kext
rm -Rf Extensions/NVkush.kext4. Install NVinject. (Assuming that the Terminal Window is still open and you are still in the /System/Library folder from the previous step.)
1. Copy the kext from your desktop to the extensions folder
cp ~/Desktop/NVinject.kext Extensions/NVinject.kext2. Set the proper permissions for the extensions folder.
chmod -r 755 Extensions/NVinject.kext3. Set the proper ownership for the extensions folder.
chown -r root:wheel Extensions/NVinject.kext4. Touch the extensions folder
touch Extensions/5. Remove the extensions cache to force OSX to rebuild it with our new kext.
rm -Rf Extensions.mkext6. Repair permissions to your drive.
diskutil repairpermissions /5. Reboot using the boot-flags -v -f
-v Verbose Mode displays useful information during the boot process.
-f Forces OSX to load kexts from the extensions folder instead of the cache file. We did delete the cache file so this is just a precaution.
