A possible explanation: I see reports here that the latest (.156) driver no longer works with HDMI for some users. (see #317) I have two displays, both connected to my GeForce 970 over HDMI. I didn't try moving them to DisplayPort.
Or, I wonder if it's something about the new driver needing NVRAM, and I'm still booting with OsxAptioFix2Drv-64.efi, not OsxAptioFix3Drv-64.efi. (https://www.tonymacx86.com/threads/macos-10-13-3-update.243852/page-10#post-1676933)
I just ran a quick test and it doesn't seem to be either of those, at least not in my case. I'm already running OsxAptioFix3Drv-64.efi, so I went and installed 387.10.10.10.25.156. Rebooted without my HDMI monitor (just 1 DVI + 1 DisplayPort), bad performance was pretty noticeable straight away. Then repeated with just the one DisplayPort display and same thing - although it certainly becomes less obvious the less pixels you're pushing, but it becomes apparent when you start displaying some WebGL content and then try minimise windows etc.
