Oh gaaawd, that reminds me, you think they will do the dumb denuvo or whatever the heck was the copy prot on PC? I remember dowloawding the cracked exe for 4 I think because the real one was so unstable and slow cos of the copyprotection.That and gta has been console first for a long time as well as consoles have a bigger gamer population with less cheating and stealing
As for the optimization... yeah that never was a strong suit of rockstar. Well actually they probably did all they could for the aging 360 that could barely run gtaV at 30fps, dipping into the 15s and stuttering a lot, but there is no excuse for gta4 being so utterly demanding and unstable on PC. I had a top of the line amd graphics card and near best intel cpu, fresh clean windows with tons of ram and fast hdd and so on, yet it was all over the place. GTAV ran kinda poorly too but that was way more acceptable at the time with my hardware.
Despite this, I don't think GTA ever had a bad launch. It usually worked for the majority with not much bugs.
