I recently bought Launchbox premium in order to have access to Big Box. Once I got Big Box setup, I started using it and it lags and there is constant stuttering in every action I do. Whenever I change games or platforms there is a little delay, lag or stuttering. Videos sometimes take time to load, and even if I'm in settings, I notice there is lag whenever I change the options. This problem happens with every theme, even with the default one. Now, this problem only happens if I use my PC, which is a decent setup. It is the following: -intel core i7 4770 k - AMD RX580 -16 GB RAM -Launchbox is installed on a clean 240 GB SSD (A new one) What I find interesting is that I tried the same Big Box setup (around 300 roms with colorful theme) in laptops that are considerably worse than my PC. An 8 year old laptop with a third gen i 5 could run Big Box without any lag or stuttering problems. Any advice on how I can fix this issue? My processor does not seem to be an issue, despite having 6 years of use, I can render videos in Sony Vegas with relative ease, and pretty much run any Triple A game without any trouble with my setup. I have already checked that core temperatures and GPU temperatures are fine while I use Big Box, so I don't know what might be causing this trouble on my PC. Hope you can help me, and sorry for my bad English, it's not my native language.
