I recently installed the 64 bit version of retroarch on my laptop....and have been trying to play some ps1 games.....its not going well. The sound and the graphics on the title screen pages are lagging. The actual game play is just a little slow...the sound is a disaster though. I don't know if not meeting system requirements or what? Ive had emulators on my phone before..so im not sure how the lap top couldn't handle it....anyway here's what im working with.
Dell inspirion 5000
2200 GHz AMD A8 with raidon R5 graphics
12 Gs RAM
Runs Windows 10

RetroArch 1.7.5 64 bit

ive been using the "beetle" cores
trying to play castlevania SOTN , have 2 bin files and 1 cue
Oh, and there is about a 15 second delay when starting the game before anything shows up.

sorry if this is obvious, and yes ive searched multiple FAQs and threads. thanks
