AotS: need more CPU cores, and if only all GPUs supported Async compute...

[bystander36]

I think people are not aware how fast today CPUs really are.Or to put it in other way;I think people are not aware how much software hides true potential of hardware.

And yes even todays fastest graphics cards cannot process all data that todays fastest CPUs can throw at them.

CPU's are very fast with linear code, but what makes GPU's great, is that with all their cores, they scale extremely well for parallel processes.

Actually,

A few months back I tested this game limiting the number of threads and the effect on performance.

If you got time, they just updated AotS to 1.2, with a new benchmark... I would be curious as to what it now shows.

Have I said otherwise?

My post was about LTC8K6 being dumbfounded that game is GPU bound at low 30s FPS.

Sure. I'll try to post something this weekend.

Any progress?

From the devs:

## Vulkan ##

This is now working in our internal builds! This might show up in 1.5. AMD is providing a lot of assistance to us in getting Vulkan support so please be sure to give some kudos and credit to AMD for Vulkan in PC gaming. It'll run great on any GPU that supports Vulkan.

I for one am waiting to see what they can do with Vulkan, since, I think this will be the first time we can compare the same engine under DX12 & Vulkan.

For win 7 people, this could be the showcase game for sticking with win 7 instead of 10 (to get DX12).

I wouldn't expect much from Vulkan compared to DX12. It seems that DX12 is more along the path when it comes to development, than Vulkan is. I mean, Vulkan doesn't even support multiGPU right now. Also, DX12 from what I've seen, has a better method for implementing things like asynchronous compute than Vulkan..

I'm not sure if you can really say DX12 is further along in development. They've talked about MGPU support for DX12, but so has Vulkan. How many DX12 games actually support MGPU when running DX12? The one example we have of Vulkan being used in a AAA game, Doom, is pretty great. Miles better than the DX12 implementation in, say, Deus Ex Mankind Divided. And it seems to make pretty good use of things like async compute and multithreading.

It's what devs have said too. That vulkan is around a year behind in terms of tools and everything.
It's still usable of course. It's just that the whole development ecosystem(I guess that's the right word) isn't as mature.

Problem is, we don't know how well Doom would have run in DX11, let alone DX12.

OpenGL is often worse for both Nvidia and AMD over DX11 in other games that offer both

I mean look at Talos:

Now I'm all for Vulkan and DX12, but we are trying to compare apples, oranges, and pineapples
