GTA IV 4K PC Ultra Gameplay (FX-8320, GTX970)

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. <br />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. <br /> <br />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. <br /> <br />On this video game has no mods at all, only Simple Native Trainer, and game version is 1.0.7.0. <br /> <br />PC specs: AMD FX-8320, 12GB DDR3, GTX970.
