Well,one thing is the quality of the port,and the other is lack of new patches,in my opinion there should be more,until it represents the quality it meant to be,but no.......sadly 18.104.22.168 was their last one and that's what's wrong,seriously.It's not alright.Sandbox games heavily rely on smooth and stable frame rates,and GTA 4 is poor on this field,game is sometimes fast,like it should be,but sometimes frame rates drops in a matter of seconds to gain normal rates,so like i said 22.214.171.124 shouldnt be the last one,as there was so much to do.And just because it's a sandbox game,doesn't mean it cant have stable frame rates.
get it if we're discussing what was wrong with GTA IV port in the past, but today if you can't run it smoothly then you won't even run GTA V at all.
Hey, that's not true. Smoothly means different stuff for different people. So let's say "smooth" is a stable 60. Some people with higher-end rigs still can't keep a stable 60 in IV.
Personally, my current PC is an absolute trainwreck. But I know It'll be able to run V, even though I won't have this specific PC by the time the game releases, since I am in the process of building a new one. But I'm sure that, if you were AT LEAST half-way there in running IV smoothly, you'll be able to run GTA V, and play very optimally at low/medium settings at that, assuming the optimization is at least as good as Max Payne 3's.
All evidence gathered from build logs and leaks suggest that GTA V is not a port. In fact, PC ports in general seem to be dying out. The only excuse for sh*tty optimization nowadays is devs either being piss lazy and not wanting to take the time to optimize for a wider range of hardware, or devs simply not being able to do it for whatever reason, technical, time constraint or otherwise.
