NVIDIA Shows Ada Lovelace's Opacity Micro Maps Feature and How It Can Boost Ray Tracing Performance Opacity micro maps should help in cases like this one where there is a lot of particles on the scene and the particles have a lot of empty space on them. The problem with empty space is that you have a single large billboard that contains that empty space, but it also contains non-empty areas, so whenever the ray tracing hardware in the GPU hits this billboard it doesn't know whether this hit is useful or not, so it will return the hit to the shader. and the shader must load the texture to determine if this hit is actually useful. If it's just empty space, the hit will be returned back to the ray tracing hardware to continue looking for useful surfaces, which is obviously suboptimal. So, we can reprocess the opacity texture of the particles and build a so-called Opacity Micro Map here, which is kind of similar to a BLAS, and then we can bind that Opacity Micro Map to the geometry and let the ray tracing hardware decide if the hit is useful or not before returning it to the shader. As you can see in the bottom picture, Opacity Micro Maps can reduce the number of shader interactions with the rays quite significantly because there is a lot of empty space in these particles, and that makes the G-Buffer pass almost 40% faster in this case.

Great conversation. I remember all of this going on around the same time I started posting again. I remember Hilbert posting an article about TSMC opening new facilities for chip manufacturing. COVID put a serious kink in the chain. As you guys know, videocards wasn't the only product affected by the lack of silicone. In my state we had many parking lots filled with vehicles that couldn't move. We now have manufacturers producing chips here that has helped with production meeting demand. Quite honestly, we are still feeling the effects. In regards to GDDR6 chips and silicone the bidding war was indeed intense. Here we are in April of 2023 and I can finally "sometimes" see a PS5 or a Series X on store shelves for a consumer to purchase. I'm seeing more products available as time passes but another factor that doesn't help is that we're heading further into a deeper recession. I do see many customer service jobs that are hiring but what's ironic is that some of these same companies collapse a few months after hiring people. Didn't mean to stray away from the topic. Great points gentlemen.
https://www.amazon.com/G-Skill-Trid...00+mhz+gskill+trident+z,electronics,95&sr=1-5 I hear ya Guru. Dude....I have 64gb of DDR5 in both of my systems. It definitely did not cost $299 back in October through December. I know this is the game we're in but man.......I'm feeling some type of way........ I will say this....I've been very happy with the performance of these sticks for the past 7 months. Both of systems scream with these. The 7950X is my production and money maker. 13900K is my main game machine.
I think those prices are too optimistic unless there's some serious cutdowns on the gpu. https://www.fabricatedknowledge.com/p/the-rising-tide-of-semiconductor Not only is the price of everything going up but we're also hitting a technological stage of whether or not something is actually going to be cost effective or just too expensive to bother making. This isn't to say the current prices aren't crap though, because they are.
I'm pondering myself whether to get the new 7200MT C30 kit, for the same price I paid for my 6000MT C36 kit just a few months back. Though probably too much work for little gain, so I will just wait and see if there are any interesting refreshed Raptor Lake coming out first before upgrading RAM along with it. Yup with the recession is coming, it's better gear up and hold out , I actually survived without salary (only 400usd/month support from my airlines) for 2 years during Covid :/
