I've just uploaded my first GTA V video using the Rockstar Editor on the PC version. I hate Tonya, and couldn't have thought of a better character to finish her off than Trevor. Enjoy it on 1080p at 60 fps!
That's some skid mark . As for the graphics, the textures are only slightly improved in PC version from the comparison videos I've seen. However, the shadow details, draw distances, and volumetric lighting are phenomenal. Having near-constant 60 FPS is also pretty nice.
Story DLC is apparently coming out, I don't know if it's tomorrow with the other DLC or not though. It has to deal with Agent 14 for the Humane Labs missions from the Heists.
