F12 for steam screenshot, maybe print screen for non steam, or use fraps GTA 4 was a mess lol, it was a sloppy port, buggy slow, and had three layers of DRM, with steam, gfwl, and social club. GTA 5 is not a port, it was built from ground up for PC I just did a 2 man heist with sorophx. Would be great to get 4 together to tackle the humane heist (most epic), or the final big bank heist (most money). I can start any heist in any order since I beat them all on Xbox already
