I've been having this issue since I bought launchbox around 6/7 months ago. First of all, these are my specs:
AMD FX-8350 @ 4.2ghz
16gb RAM ddr3
Gforce GTX 580 x 2 SLI
Windows 10 Pro
I can run games like Witcher 3 and Dolphin at 60fps with no issues so I don't think it's a power problem.
I have massive stuttering going from one game to the next. It's like it freezes for 1/4 of a second until it loads "something". It's not only a coverflow issue, even in the main menu the platform wheel art stutters pretty badly when I scroll. It's not a cache issue either, I tried having only one system with 10 games and the performance was still bad. The only view that runs perfectly is this one:
No stutters there, even the transitions work perfectly.
Trying to narrow down the issue, here are the things that I've tried:
Formatted C: drive and installed Windows 10 from scratch.
Re-Installed Launchbox on SSD.
Disabled SLI
Force triple buffer / vsync in the drivers.
Lock 60fps with Rivatuner.
Tried both 60hz and 120hz.
Force CPU to run in performance mode.
Gave Big Box admin rights.
Run Big Box in compatibility mode.
Disabled display scaling.
Updated GPU drivers.
Disabled all those useless Windows 10 services.
Lowered the quality of the covers.
Disabled all the transitions.
Lowered Big Box framerate to 30.
I honestly have no idea what's the problem. CPU and RAM performance seem fine:
GPU goes crazy though:
So I dunno, that has been my experience with the issue so far. Any ideas are welcome.
