I recently had some nostalgia for Grand Theft Auto IV, so I launched up today to check how it works on my actual PC. As it's widely known, game's optimization on PC is really poor.
In my case, it runs at ~30FPS (can reach +90 on interiors) no matter what resolution I choose, so I set the game at 4K (using Nvidia DSR), and here's the result.
Ignore the noobish gun gameplay (too long since I played the game for the last time), and sorry for not having a FPS counter, I should include it for next videos like this.
On this video game has no mods at all, only Simple Native Trainer, and game version is 1.0.7.0.
PC specs: AMD FX-8320, 12GB DDR3, GTX970.
