Re: How does DSC affect image quality?


I would be more than happy to answer any questions regarding using the console tool to get the results but you are not asking them, you just expect the result.

All of those modes are same number of pixels/sec processing. Quadrupling refresh rate ability via 4x DSC allows a large 4x motion ...

Sure, here's the result. (losslessly compressed output from DSC)

Re: How does DSC affect image quality?

Can we get before/after images of DSC compression?

Re: HOWTO: Using ULMB Beautifully or Competitively



Excellent post, thank you.

If I can drive 400 FPS in Overwatch and have a 240hz monitor w/ ULMb it sounds like I should either cap the game to 240 frames (frame rate = hz) or run 400 fps uncapped.

If I cap to 240 and fps never dips below, do I still need to run Vsync? Or because I can keep ...

Re: Is TN always the king ?!

OLED seems to be better than both and they will release the higher refresh rate stuff soon. It already made its way into laptops.

Re: ASUS ROG Swift 500Hz Announced!


Damn, such a refresh rate would obviously be very difficult to achieve without interpolation. :shock:

Oh yeah, why is everyone promoting 1000 hz? It seems like in order to make the display completely clear of blur, its frequency should be 2-4 times higher than its horizontal resolution (correct ...

Re: Even rendering 1/4 of the pixels looks decent if you just black out the other pixels

Part of the motivation of making the post is that the interlaced version already looks good at 60 FPS. That is, until you scroll vertically and it's missing details. I'm guessing it's showing the details based on the exact pixel, but the location of the UFO moved so you show the alternating pixels ...

Re: Pixel response time way slower than refrash rate

Is overdrive on? That usually improves it at the cost of overshoot

Re: How to remove flickering of objects smaller than the display pixel size?



But the question is how to remove this, other than the option of buying a display with a higher ppi?

It's called "subpixel shimmering," and the only thing that can mitigate it is certain forms of TAA and legacy SGSSAA (the latter of which no longer works with most modern games now that they're ...
