Another strike against going fully digital.

The GTA 5 psn release already had problems enough with the 18gb download, leaving some users with a corrupt install.
Earlier Rockstar advised against installing both discs on 360, now Digital foundry has also confirmed that the psn digital version performs worse then the disc based release. The same streaming issues in a game optimized to use both hdd and optical drive.

Taking the PSN route to Los Santos turns out to be hardly convenient or cheap, nor the most technically refined way to play the game. In our experience playing from a newer Western Digital 500GB HDD the results proved less glaring, suggesting faster drives may yield improved performance, but if you'd rather sidestep the issue altogether then we'd recommend sticking to the retail Blu-ray copy.

What does this mean for openworld games next gen. Both consoles get faster CAV drives, better suited to gaming, but are also going to ignore those extra resources by doing full disk installs. Seems like a waste to me.

Bad... really bad.

I haven't had any issues using 6gbs hitachi 1tb hdd

One incident is hardly a strike against going digital, and the 360 version its the opposite, installing 2 discs causes an issue digital doesn't. it will be fixed.

Installing the second disc is having the same issues as the digital version, not opposite.

Reports are circulating that the PSN version of Grand Theft Auto V suffers from the same issues as Xbox 360 copies do when the play disc is installed.

It should be obvious that:

digital + last gen consoles and game = aids in a box

but

digital + next gen = sweet baby jesus

Down with digital!

Xbox360 has issues in the physical release, PS3 in the digital release. A perfect balance of hilarity.

Dat digital future!!!

My physical copy works GREAT.
