Since the last update I noticed grains on the shadows on the red/green dot attachment. I still didn't notice it anywhere else because as soon as I noticed I reported. If I'm not mistaken the loading screen (with the picture of the map) also has some grains on the shadows. I will update in case I see it somewhere else.
All the setting were on high. I also made a video where I changed to ultra but the problem persists (I will upload the video and link it here later).
No video settings have been changed since the first release.
My GPU is a Radeon HD 5670.
