I played with a Ryzen 5 5600X and typically ran at 4kp40. This doesn't answer your question since you asked about 60 fps but apart from a few places in Act 3 where I got stuttering when entering a crowded street I was able to run around 40 fps. I did not have the frame rate displayed with the...

I don't think a virtual texturing system will ever read just 10 texels. It will read an entire page of texels which is at least 4kB. I expect systems will then pull the data into vram and read it from there until a heuristic results in the page being evicted from vram. I'm sure there are...

A low frame rate doesn't mean low power nor does high FPS necessarily mean high power. When there is correlation between low power and low FPS it probably means low utilization of resources and that is the reason for the low FPS.

I haven't looked at Metal3 but I expect there are subtle differences between it and Direct3D's definition of Mesh Shaders.

I don't know why you were down on PC gaming. Consoles are having the same supply issues.

That's good to know. My desktop still has a Phenom II and a Hawaii GPU and now that the Ryzen 5 5600X is starting to get back in stock I'm ready to upgrade.

If you have excess solar power why is it an ecological disaster?

In one of the videos Brian Karis or someone else from Epic said they are developing tools to reduce storage later in the project's life cycle. The goal is for artists to not need to worry about storage early in the project.

After seeing the breakfast picture zed post prior to this post I was thinking of artery saturation rather than compute saturation.

No, the other way would have been to overload the rasterization path with geometry so hardware vendors would have been forced to increase geometry performance or lose benchmarks. Nanite may be a disincentive to improve hardware rasterization performance for small triangles. Nanite is a GPU...

Developers can complain about hardware rasterization and that it doesn't meet their needs or they can do something about it. Those like Sebbbi and Graham indirectly drove the development of the Mesh Shader API by using compute for GPU driven rendering. The other way to go about it is to create...

My understanding is LOD isn't free with a BVH, it depends on how it's organized. I recall a Siggraph 2014 panel about this and while I didn't take good notes Blue Sky Studios said they created a sparse voxel octree for each asset in Rio 2. This gave them level of detail but cost a lot of disk...

No. I was only commenting about the Mesh Shader stage. I can't go into details, but at least wanted people to know the differences are manageable.

The patent describes the version of the primitive shader that is fit into the traditional graphics pipeline. There's also a version that launches like a compute shader that has existed from day one. The problem was it didn't quite support the Mesh Shader API. It's close, though when creating...
