Hackintosh Yosemite not working properly?

Question

hackintosh

I have one problem, for some reason the animation is dull www.youtube.com/watch?v=QRmRJpxuws0,DSDT and SSDT I corrected, the video card is native, I ran the system through different benchmarks, everything corresponds to the system performance. I can't figure out what the problem is.
CPU type QuadCore Intel Core i5-4670K, 3400 MHz (34 x 100)
Motherboard Asus H87M-Pro (2 PCI-E x1, 2 PCI-E x16, 4 DDR3 DIMM, Audio, Video, Gigabit LAN)
System memory 12193 MB (DDR3 SDRAM)
Video card AMD Radeon R9 280X (Tahiti)

the same trouble, all jerky on p8p67 deluxe b3\ gtx 650 ti boost. I can’t decide for the second year, because of this I don’t use hackintosh. google is silent. somewhere I saw a guide on editing gpupm, sometimes it helps with this kind of lags

Today I decided to experiment. Fact: if you change the monitor resolution to 1600x900, all interface lags disappear, if you change to 720p, lags appear again. There is no point in sitting on 900r, but it is interesting to find out the reason for this behavior
