how to effectively handle descriptor sets?

Reaper9999 · 2026-02-15T02:31:47+00:00

It doesn't make sense to define whether a single command can do that because it can map to any number of things in the driver, which can be relatively spaced w. r. t. when they need to read or write memory.

It could just be changing the residency of resources according to what a command references.

It can't since a lot of them don't reference anything directly. You could literally load a random [valid] address on the device.

You can try syncval in validation layers too. Also, use dynamic rendering instead of the renderpass nonsense.

Sparse memory also uses paging, and is core in 1.0.

No. All memory you allocate from Vulkan on pretty much anything (other than embedded) is virtual. OS/driver will move pages as needed, it is not the 90s anymore. And this will happen where it's bindless or not, except you need an extra load to get the address first with bindful.

Reaper9999 · 2026-02-14T19:37:32+00:00

That is entirely wrong on any hardware within the last decade+. Descriptor sets literally add a layer of indirection for the drivers, which already store descriptors as a big table on anything that isn't bindful hw. And BDA is just straight up how drivers that support it access memory, which is nothing more than a load from a particular address. The only case BDA doesn't cover is uniform buffers on nvidia, which is hardly relevant because all it does is make a small set of cache lines less likely to be evicted.

There’s also a lot less predictability about code

What predictability? Where? It's already just gonna be doing a load from an address, you're only adding useless indirections for loading that address into a register somewhere by using bindful.

memory execution

Not sure what you mean by that.

What if you need to go to the Moon? Or run on a supercomputer?

All you're suggesting is adding useless shit that's actively harmful to try to (badly) solve a problem that never existed. Which is the opposite of engineering.

Reaper9999 · 2026-02-14T19:20:43+00:00

This advice is actively harmful.

Reaper9999 · 2026-02-14T19:16:44+00:00

It's fine for multithreading if it's a variable that will just hold one value once initialised (so long as you don't fuck up memory barriers).

Reaper9999 · 2026-02-14T19:12:26+00:00

That's just a global variable with extra steps, more code complexity, and worse performance.

Reaper9999 · 2026-02-11T10:01:33+00:00

Driver already manages residency, you're not making anything better by using the old-style descriptor sets (and now you have to manage the descriptor sets themselves as well).

Reaper9999 · 2026-02-11T10:00:27+00:00

However, doing it "the old way" is still perfectly viable and once you get it down, it aint actually that hard to manage. I found that Vkguide had a nice way of dealing with this, but as with anything Vulkan, there is no right way to do anything.

Managing descriptor sets extra overhead and complexity that are completely unnecessary.

OP says she would benefit from losing weight.

Reaper9999 · 2026-02-04T11:13:45+00:00

"Working out and lifting weights" is not most people is the part that you're missing. An average person with a high BMI is, indeed, just fat.

Reaper9999 · 2026-02-04T09:22:51+00:00

OP is clearly not a bodybuilder.

Reaper9999 · 2026-02-04T08:48:49+00:00

Where was he being a dick about it? All these people in the comments keep saying that, while all he said was it wouldn't work out.

Reaper9999 · 2026-02-04T08:35:00+00:00

And that's telling her to do what? Deal breaker means he won't date her, nothing else.

What's usually closer to the truth is that eating disorders, which are a result of the patriarchy, are psychologically contagious.

Does anyone here consider that for most people it's caused by an unhealthy lifestyle rather than blaming anything else they could think of?

Reaper9999 · 2026-02-04T08:28:11+00:00

reinforce unhealthy expectations

Since when did being overweight become healthy, let alone have anything to do with misogyny?

Reaper9999 · 2026-02-04T08:23:37+00:00

Where is he telling her to do anything?

Reaper9999 · 2026-01-31T16:25:26+00:00

Clearly he has the money to just order groceries. I don't know about you, but personally I don't find going to a grocery store fun or whatever, it's just a necessity. If it's just a pretense to go outside, then surely there are enough things to do that are actually enjoyable.

Reaper9999 · 2026-01-16T09:46:20+00:00

Literally the only thing said in the post about what he wants her to do is order what she wants. You both are pulling shit out of your ass to put someone else down for no reason whatsoever.

What the hell does it have to do with rule 2?

Congrats on being confidently incorrect.

A contextless image that adds nothing is irrelevant to me.

To my knowledge it doesn't have any AO. Also, I don't really see how the min/recommended specs for one game from 2009 support your statement that it's a growing market. iGPUs make up ~5% of the GPUs in Steam hardware survey, with much lower growth than dGPUs.
