Nvidia has released new GeForce graphics drivers that seriously improve the performance of BioShock Infinite and Tomb Raider.
By installing them you can boost BioShock Infinite performance by up to 41 per cent, and Tomb Raider performance by up to 71 per cent.
There are other games that benefit to a lesser degree as well.
"314.22 WHQL is an essential update for all GeForce GTX systems," wrote Nvidia's Andrew Burnes.
There are graphs - if graphs are your thing - on the Nvidia website. They chart the performance increase across various games.
