Since some of you mentioned the games I was thinking about...
If console->PC ports are allowed there's an enormous list, but I'd say some recent console->PC ports:Batman: Arkham Knight
Had terrible performance on PC despite playing with CPU and GPU with more than x3 or x4 raw power
compared to the consoles hardware, even being downgraded visually, and initially limited to 30fps.Tales of Symphonia/Tales of Zestiria
(officially now mostly fixed taking from unofficial fix)
Bad frame limiter (and at 30 fps too) and capped at 720p (Symphonia). Many many bugs of all kinds,
from localization bugs to un-synced cutscenes to plain crashes. Not to mention this ToS comes from the
downgraded PS2 then scaled for PS3 port, instead of taking resources from the original GC version.Final Fantasy III/V/VI
(not fixed AFAIK)
Plain obvious, but also... terrible gamepad compatibility, inappropriate UI, generic bugs, crashes, savefile
corruption and/or deletion, and even not being able to advance past a certain point in the game (FFVI).Final Fantasy XIII
Bad frame limiter and capped at 720p resolution.Final Fantasy X/X-2 HD Remaster
(now fixed, unofficially)
No way to choose Japanese voices (though present), bad frame limiter, and capped at 30fps.Dead or Alive 5 Ultimate
Instead of porting the graphically enhanced version for PS4 and XBO they went with the older consoles' version.
Plain, simple, ugly. And no enhanced physics
Those are the ones I remember most.
P.S.: Oh, wait, FF7/8/9 too...
