It got me really hyped at first. It seemed like magic. Unfortunately, after a short while the novelty wears of, and you just notice the flaws.
The dual monitor experience is bad. You get to upscale one screen at a time, which is whatever. That's understandable. But it then locks your cursor into that screen, like as if it was a fullscreen game. Alt tabbing makes the screen stutter and flicker awkwardly each time. Your cursor becomes sluggish.
In video playback, using any sort of controls causes issues. Scrubbing through the video causes sluggishness, flickering, just making the whole video display go black permanently until you alt tab, and so on.
So user experience wise, it's just very sloppy, and simply subpar. But what if you just let the video or the game play and you don't touch anything else? Well, even then there are big downsides.
Input latency is noticeable, and it does make the experience worse. It requires a sizable performance overhead, like a base fps of 80 to be able to sustain 60 with Lossless Scaling to double it to 120. If that sounds like a win, remember you now have input lag, as well as noticeable ghosting/shimmering around your 3rd person character when you turn the camera.
When 80 fps is already smooth, is the 120 fps experience really an improvement if you consider the flaws? Not to mention having to turn it on each time. Granted, it has some autolaunch functions built in, but again, setting it up for each game? Have fun with that.
So yeah, it was neat to play around with for a while, but it's just a gimmick in the end. Also consider that it hasn't been updated for a year, and from what I've heard the dev cashed in his earnings and moved to some tropical island to retire, so it's not going to be improved further or fixed.
