GTA V is great to play on PC, but not if you have a really low-end PC. GTA V modder ’emirh08′ has compiled a mod that will allow you to play the game at good frame rates (over 30 FPS) on an average system with low specifications. On a Microsoft Surface Pro 2 Tablet the modder is able to get over 30 FPS on 1280 x 800 resoultion with textures at maximum, FXAA and Shadows enabled, reflection quality on high and Anisotropic Filtering at 8x.
The Surface Pro 2 has Intel HD 4400 graphics and a 4th generation 1.6 GHz dual core i5 processor with passive cooling. Keep in mind the official system requirements for the game are:
Processor: Intel Core 2 Quad CPU Q6600 @ 2.40GHz (4 CPUs) / AMD Phenom 9850 Quad-Core Processor (4 CPUs) @ 2.5GHz
Video Card: NVIDIA 9800 GT 1GB / AMD HD 4870 1GB (DX 10, 10.1, 11)
Sound Card: 100% DirectX 10 compatible
Here are two videos of the mod in action!
