Need some help with older hardware/sleep?

Hey there...

Found myself an MSI B85M-e45 mobo + i5-4460 PC with 8GB RAM, SSD + HDD and 4GB AMD RX 560. I have latest Mojave 10.14.6 installed, and recently patched XHCI to get (Intel) USB 3.0 working. Everything seems to be working fine, but after SLEEP, I lose graphics acceleration and Ethernet (to name the only two I have checked - it is so laggy and unresponsive as to make further testing a real chore). I have patched AMD9500Controller.kext, and I also used AGPMInjector kext. I have renamed EC0 and H_EC to EC.

I have found a DSDT.aml for my motherboard that appears to be patched (it has DTGP item at the end), and I am about to test it...

If anyone has some ideas on how to treat this Haswell system (does it require XCPM???) then I would be VERY INTERESTED :-)

I am yet to map the USB ports thoroughly, but I cannot see how the symptoms relate to USB (no USB ejected errors on wake)?

PS. I have not used RadeonDeInit, as I am not suffering from the black screen issue at all

Help me Obi Wan, you're my only hope.
