Rock64 as a retro-gaming console: early impressions

[Luke]

Wow, it looks very good, have to find the way how to install PSX core

Its installed. Just add games to the PSX folder (there is smb running - you can just do it over network) and restart EmulationStation OR reboot.

How did you compile parallel-n64? I could install it on my PBP but not make it work using these options: https://github.com/libretro/parallel-n64/issues/633

So I just picked up a Rock64 1GB board and I'm questioning the performance of PSX and N64. 
I see lots of comments about how it works very well, but that isn't my experience.
For example Ridge Racer (PSX) is basically unplayable (large pauses and lags), which doesn't seem inline with other peoples reports.
Looking at the monitoring tab in recalbox manager its seems that its pretty much maxed out on RAM, is this my problem? Are the people reporting good performance using a 2 or 4GB board?
I don't have a problem if this is just a hardware limitation, just trying to find out if its a limitation of the SoC or if maybe the mSD card is no good (its a Sandisk branded one but very much could be a fake).
