I am at the 4th iteration on the pixel inspector and light path debugging tool. Eventually I moved the path collection to the GPU, so I don't have to toggle between CPU and GPU rendering, making the visualization fully interactive.

That looks extremely useful and well done! Totally stealing it for my future renderers :D

nice, I always wanted to have such a feature in the renderer!

Hehe. Me too, I don’t have much time available to fix light transport issues; good visualization, plus the ability to repeat the path on the CPU with a debugger are key.

"This will be the [fourth] time we have [rewritten] it, and we have become exceedingly efficient at it" Well done!

Hehe, more like the fourth time I come back to the feature adding bits and improvements. Actually, this is still using the first implementation core 😄

Wow that’s super neat, so the path collecting visualization is all gpu, no readback inbetween? 😃

It does read back. The paths visualization is rasterized on top of the path traced image. But the earlier iteration was running on a matching CPU path tracer.

Monad Testnet Visualized (Pt 3) I think Claude and I have fixed the freeze/pause issue. Works a lot smoother and most of the jitter is now just due to my GPU/CPU begging for mercy trying to handle the data visualization

Breaking down the difference between CPU and GPU. This is such a joy to watch.

I tested this on the 4070 Super, and while there is a performance difference, it’s not huge. The GPU also pulls more power on the older driver. If you’re using Path Tracing and have a higher-power 40 series GPU, it’s still worth trying, you might see a bigger performance boost.

Stress testing Metropolis 1998! - Population: 53,500 - CPU FPS: 80 - GPU FPS: 10-80 - RAM: 3,100 MB So: At the moment, the game is GPU bound. I know why and there's a lot of room for improvement. It will involve developing or customizing an existing GPU framework. There's also a lot of room to improve CPU/RAM, but right now it's in an okay place. #gamedev

I tried Motorstorm on RPCS3 and can confirm it is playable. However, terrain deformation is extremely taxing on the GPU so I can't have 60 FPS at 1440p on my RTX 3070. You will have to either drop the resolution or lock the framerate to its original 30 FPS cap.

Today I release new GPU Particle Volumes system and the GPU Snow Particle shaders for it! This snow shader can render hundreds of thousands of particles at the same time even on a weak GPU. It also supports VRC Light Volumes. Get it on my Booth or Patreon!

"Use the GPU to optimize the rendering" >30fps on a 1000x1000 map. Absolutely crazy. The switch to simplified hexagons (solid color) isn't even needed btw, I just think it looks cleaner.

As of today, the Phoenix Suns have failed their fans, Devin Booker and Kevin Durant. There IS a path towards redemption, but from what I have seen so far, I am not confident in the Suns following that path.

🚨 SPENCER PRATT: "Thankfully, I married an angel who was very connected with Jesus and has brought me to the light." 🙏🏻 "I was always not so bright in the light on the Lord's path here. And thankfully, my wife has always just been so connected with Jesus and God." "It's been very empowering to just pray and just be on his path and just say, God, if you want me to save these animals, save these humans and protect my city, just keep putting me in the place where I can do that. And if it's not God's plan, it won't happen and I won't have that pressure and that burden on my heart that I now feel because I am so close to being able to do it."
