[Choppy performance and stuttering issues in Retroarch and other emulators (SOLVED)]

Actually its possible its your motherboard or your connection/cable, that IGPU does do 4K60 but you need either a HDMI 2.0 port and cable, or display port. Standard HDMI ports and standard HDMI cables that are not 2.0 certified can often do 4K30, but they dont have the bandwidth for 4K60. If i was you i would look into it, it could be that your motherboard supports 4K60, but you simply have a non spec HDMI cable without the needed bandwidth to transmit 4K60.

You are right, I am doing 4K (3840 x 2160) at 60Hz!, before I had my resolution set  to the highest (4096x2304), which was causing the stuttering. I forget that 3840 x 2160 is actually 4K
btw, I have a Intel i5, 4570T with DisplayPort 1.2 to HDMI which can push the 3840 x 2160 @ 60hz to the TV just fine.
 

[Best Way to use Launchbox with NAS system]

@peterrrjr With all your roms being served up from the NAS, where does performance/responsiveness/time to load, hit a wall? Do you serve up GameCube, Dreamcast, Wii roms in a timely manner?  Are there some platforms you just host locally?

I have a Lenovo m93p, Intel 4750T with a 256 SSD, 16gb RAM, and Gigabit Ethernet connection to a Synology 918+ with plenty of space.

I prefer to to have hard links (junctions) from my local Launchbox's Game, Video, etc folders to the NAS folders. Thanks for the advice!

[Choppy performance and stuttering issues in Retroarch and other emulators (SOLVED)]

Thanks to this thread, I realized that my Lenovo m93p's integrated Intel 4600 can only output 30hz when running at 4K, which for me was causing the choppy audio as you mentioned above.

Switching the resolution down to 2K~ and a min of 60hz refresh rate solved the issue. Thank you!!
