CHD MAME Game Initializing Issues

[topher_csr]

Hello all, 

I have used Launchbox as my front end for a few years now and at one point had a fully working arcade setup. I took it apart tp upgrade the PC and when I went back with it, im having issues with MAME CHD games either not loading,  or taking forever to load and being sluggish till you get past a certain point. Im running a .255 merged rom set, using MAME as the emulator and the PC is more than powerful enough to play the roms.

CPU: Ryzen 7 3700X

GPU: RTX 3080

Storage: 2 SSD's: Launchbox /OS on one, all Roms on the other.  

 

What are some things I could try to fix the loading issues? It will take around 5 minutes to get through the initiating screens with all the CMOS test stuff. I tried to enable skipping that part and had crazy emulation issues. Nothing should have changed from the older setup that played those games flawlessly.  Any ideas are appreciated !
