If I use any SMBIOS higher than 14.x I get some funky screen latency/lag. It disappears when going down in SMBIOS. Does the SMBIOS has any functional value?
Yes, it has functional value. iMac14,2 doesn't require IGPU to be enabled on systems that had dGPU for Preview and Quick Look to function. On an old build that I had, using incorrect system definition prevented CPU speed steps from working right.
You should match system definitions that come as close to your CPU and motherboard chipset as possible.
You can try manually entering the following in to your config.plist to see if it makes a difference. Are you using DisplayPort or HDMI? 4K monitor?
