I just got Batocera 35v and did my first install on my PC (i7 5820k, x99A, 16go DDR4, RTX 2080). My connection for sound, S/PDIF Optical digital audio output to my amp. Batocera is installed on a WD external 4to drive.
With this beautiful configuration I have the impression of having slowdowns or in any case a feeling can be simply hatched sound or sound lag. On my first tests for example with Mame 2003 and the game 1942j (non-margined Mame 2003 version) or with SNES-MSU1 where the sound is not complete (just the sound effects and no music) and very hached or lags…
I reseach where the problem comes from : hardware incompatibility? Driver problem, NVIDIA for example (I didn’t modify the conf file manually for my GPU, but in the system information openGL is in NVIDIA)? or a configuration problem, for example sound? or a reading speed problem on my hard drive (not SSD, speed: +110mb/s) USB 3.0 not fast enough?
