Hi @rsn5746, just FYI, performance should not be poor with 4,000 games. LaunchBox usually handles that kind of load with ease. Also, this day and age, the notion that .NET is slow is outdated and incorrect. So much so that Microsoft is building large portions of Windows itself with it. I'm constantly improving the performance of LaunchBox, but it sounds like there might be some other kind of issue going on, because LaunchBox is much more performant than that.
