Everyone ported down from the PS3 remasters to the Vita, rather than doing a brand new port of the original games themselves. Of them, I think that only MGS3 worked out rather well, barring the goofy setup they had to figure out for the controls. Everything else was either compromised but acceptable, like the Sly games, or, well, this, with little in between.
One of the biggest knives in the Vita's chest, imo. They could have made the definitive portable ports of those beloved, family-friendly IPs to sit next to Minecraft etc to really boost the Vita... shame.
Does Boost Mode help PS2 classics performance? Quite surprised at the severity of the frame rate dips here.
I think i heard Star Ocean 3 ran 5-10 average fps higher on Pro. Definitely felt really close to 60 when I played with Boost mode on
