My game crashes when i put my resolution to full screen. Ive tested this and its the problem because I can play all day in windowed but as soon as i put it in full screen i get crashes. My system is a 5950x, x570 asus crosshair viii hero mb, 32gb’s 3600mhz cl16 ram, asus strix 2080ti, evga p2 750 watt psu. My display is a dell alienware 3440×1440 120hz gsync display. I had zero problems when i had the 2080ti with a 9900ks with the same monitor. Not sure whats going on tried a fresh install that didn’t help. I know it’s something with fullscreen because I’ve tested for hours and it’s repeatable. Made me so mad I’ve started playing on my second rig a 9900ks and sapphire nitro 5700xt se on a 1440p 144hz display. Maybe I should go back to intel mainly because since going amd ive had more problems. And that’s not me just being a fanboy. I probably have more amd than intel cpu’s at this point.
