A few days ago, we informed you about the first fan-made tech demo for NVIDIA Reflex 2. Created by PureDark, this fan demo gave us our first look at NVIDIA Reflex 2 with its Frame Warp tech. And now, we have a new version of that tech demo that fixes one of its most crucial issues.
For those who did not know, NVIDIA Reflex 2 is a new version of Reflex that was announced in January 2025. The main feature of Reflex 2 is called Frame Warp. Frame Warp makes your game feel much more responsive, helping you aim faster and react quicker. It works by taking the newest camera position from the CPU and adjusting the last frame made by the GPU to match it. This happens right before the frame appears on your screen, so your latest mouse movements are shown instantly.
Now, the biggest issue of the first version of PureDark’s tech demo was the visual artifacts that could appear at the edges of the image. And, to my surprise, the modder has figured out a way to fix them.
But how, you may ask? Well, the modder used a simple hack. Basically, he rendered extra pixels outside of the screen, 25% to each direction. By doing this, we can avoid the visual glitches at the edges.
Rendering extra pixels will obviously bring a slight performance hit. To make sure there isn’t too much overhead from rendering them, PureDark used variable rate shading to render the pixels beyond the screen at a 4×4 shading rate, which is like only 1/16 pixel count.
You can go ahead and download the new version of the demo from this link.
Sadly, this second version could not run on my NVIDIA RTX 5090. Like a lot of people, I was getting a “failed to create texture shadingrateimage, error code = 0x80070057” error. PureDark said that you need to enable resizable bar for the demo to work, but I’ve already enabled it. So, I don’t know how to fix this.
Enjoy and stay tuned for more!
