Hey everyone, been a while since there has been big news related to FSR.
I’ve found some news about two upscalers that have added support for FSR upscaling. While it’s never as good as a native implementation, it’s now applicable to ANY window. Add FSR to Microsoft Excel if you even feel the need to, nobody can stop you now.
The two programs I’m talking about are Magpie v0.5.2+ (written in Chinese but free and open source, it’s what I use. Simple enough to navigate through even if I can’t read it.) and Lossless Scaling v1.4.0+ on Steam. The latter has some issues with oversharpening from what I’ve read, but otherwise should work well.
These are ‘overlay’ techniques, and take any window’s output to upscale, so it scales UI elements and post-FX with it. A true FSR implementation would come before post-FX and UI layers.
Anyway, I went ahead and put it to the test, and it works surprisingly well! It doesn’t look too different from the TAAU where the latter is shown at it’s best - static images. But because you can use the ‘native’ TAA at 100% render scaling (or more) to upscale, you lose most of the drawbacks of TAAU in motion. Win-win!
Unfortunately I am unable to give accurate scaling results for lower resolutions, say 900p to 1080p or 1080p to 1440p, as it can only scale to full screen resolutions - 4k in my case.
None are compared to native 4K, but rather compared to each other at the same resolutions. FPS overhead is as expected, around 10% for FSR with this workaround method. Seems to be on par or slightly faster than the in-sim TAAU.
Cropped comparison images below.
Test 1 - ~1200p to 4K - Native > FSR > TAAU
Native (1200p image + default Photoshop scaling to fit 4k)
TAAU (Note how it skips over scaling the display, unlike FSR scaling the Sim’s entire window)
Test 2 - ~1520p to 4K - Native > FSR > TAAU
Resolutions higher than these (~1800p and up) are virtually indistinguishable during gameplay. FSR has slight win over TAAU with sharper edges.
