Whamba. This is running on high-ish settings, nothing set to ultra and no downsampling.
Yeah, it's your core clock like we talked about earlier. It should at least be easily doubled. I know you said you tried Street Fighter, and it was fine. By fine do you mean it played the same and said 540hz, or it had normal core clock use?
Do you have any other recent games you can try (preferably 3d ones that are taxing). When I had the issue, The Division wouldn't even load up for me anymore.
