Hello all,
First off, this is my first post! So long story short, I built a family PC that is hooked up to a 4k TV with a Intel i5 6500, 8GB of DDR4 RAM (PC4 17000), and an SSD. I didn't buy any graphics card for it, so it's using the Intel HD Graphics 530. I've been using this to run Project64, and have been able to play Mario Party 1/2/3, as well as Super Smash Bros. and Mario Kart 64, all with very little to no problems. Recently, I purchased a bluetooth SNES controller from RetroBit, and thought it would be great to get the SNES games going for my parents.
So what I did was disconnect the computer from the living room, and brought it into my room, and hooked it up to my monitor via HDMI. I downloaded RetroArch, got some ROMS, set up RetroArch into LaunchBox, as well as the controller, and all games were playing well. So after all was said and done, I moved it back into the living room and hooked it back up to the 4k TV. While trying to run a game though, it was slowed down considerably. I tried downloading the other cores and changing it within LaunchBox, but to no avail. I tried using BSNES Balanced and Accuracy, as well as Performance, all with the same result. Nothing changed, in fact. I tried opening RetroArch outside of LaunchBox, and running a game like that, and still got the same issue. What was odd, though, is that I downloaded SNES9x, and ran it outside of LaunchBox, and it ran at normal speed. I tried putting SNES9x into LaunchBox, but couldn't figure it out.
Could someone shed some light as to why RetroArch would slow down after moving it to the 4K TV in the living room? It played well on my monitor, which is 1080, but I doubt the resolution is the cause. Any ideas?
