The graphical performance of Watch Dogs on PC has been criticised by gamers, complaining that high end systems are unable to run the game as they hoped, but the game's graphics technical director Sebastien Viard has come out in defence of the hit open-world game.

"Watch Dogs can use 3+ GB of RAM on NG consoles for graphics, your PC GPU needs enough VRAM for ultra options due to the lack of unified mem," he Tweeted.

"If you experience lag/stutter on a fast PC, try to lower one of those settings to reduce the GPU VRAM usage: texture quality, AA, resolution."

Viard added: "Making an open world run on NG & CG consoles + supporting PC is an incredibly complex task, the team did a fantastic job. Congrats guys! :D"

However, PC gamers may get a helping hand in the shape of a patch.

"Our PC progs are also currently working on a patch to improve your experience thanks to your reports, stay tuned :)" he concluded.

The PC version of Watch Dogs has also suffered because of issues with Uplay.
