How To Fix Slow – Lagging Preview In Yosemite 10.10.1 On Haswell Laptop

On my HP 15-u011dx x360 – i7-4510u and HD 4400 graphics, the preview of Yosemite 10.10.1 was so slow, lagging and washout color. The Graphic kext seems to load fine. Thanks to Rehabman again, I added 2 FakePCIID.kexts and it did solve the problem. All we need to do is to put the 2 kexts in the Clover EFI/Clover/kexts/10.10 folder for them to load every time Clover boots.
