I have been running GTA V on my PC with no problems whatsoever, however after my upgrade to an Nvidia Geforce GTX 555, I am experiencing micro-stuttering which makes the game not-so-nice to play. However, I am getting 50-60FPS average. My old graphics card was a 9800GT 1GB, and with that card I had no stuttering problems. Any help? thanks. P.s I have the latest nVidia driver installed.
