Quick specs: i5 7600k 16Gb Kingston HyperX 2400MHz Gigabyte 1080 Waterforce WB Win10 Acer 144hz Gsync panel, 1080p So, DSR is kinda fun. It's a very very subtle effect when you render in 1440 on a 1080 monitor, but it's a little nicety I like to enable on older titles where I'm already 144fps locked on ultra settings. Thing is, it works flawlessly for the first game I run after a fresh boot. Every subsequent run though, awful choppy constant micro stutter and screen tearing. Doesn't seem to matter which titles are first and subsequent, the pattern remains constant. I don't even know where to look. It's not hugely important, of course, but it's baffling.
