Amd Cpu Overhead


Awareness and voting with wallets will drive AMD to improve. My guess is, the reason driver command lists never caught on with developers or AMD was because it wasn't worth the trouble. Face it, most games aren't CPU-limited, where this feature shines. This is slightly different than doing multi-threaded command lists in the driver (which chunks up a command list into multiple parts, to process on idle threads).

Copypasta articles sourced from other websites are not allowed. Its not AMD limiting it to one thread, its dx11 AFAIK. My question to Dx12 though is it's capability to use 6 threads. You might say that with that advertisment for the CPU/GPU optimization guy some months ago, something might happen. http://www.overclock.net/t/1573982/amd-gpu-drivers-the-real-truth

Amd Cpu Overhead

Isn't multithreading related to CPUs? Password Videocards - AMD Radeon Catalyst Drivers Section In this section you can discuss everything AMD Catalyst related. It is also possible to execute a command list multiple times to replay a sequence of GPU work against different input data. DCLs always have to be done in game.

When developers talk about multi-threaded rendering with DX11, this is what they're referring to. Amd Reddit Often, the CPU's usage will increase substantially, causing the GPU usage to reduce overall. Rule 3: Be civil and obey reddiquette. At this point any game or application can take advantage of the feature, and not just Civ V.

Nvidia Vs Amd Cpu Overhead

offloading implies you are making the cpu do gpu tasks. http://gpuopen.com/performance-tweets-series-command-lists/ So what is the conclusion? 1. Amd Cpu Overhead The program needs to setup a bunch of objects and then pass that on to the video drivers and finally to the GPU. Amd Vs Nvidia Cpu Usage AMD Roy tweets are mostly trolls and nothing interesting and i wonder why AMD promotes them.

GTX 750 Ti Loss: -7.69% R7 260x Loss: -8.33% Call of Duty Advanced Warfare The R9 270x again. They had some of the best kernel/driver engineers in the world to do it, and literally thousands of full blown real world test cases. Source OneSource Two Nvidia not too long back decided to fully support Direct-X 11's capabilities with their "wonder driver" which promised the following:Source It would seem Nvidia had fully enabled all AMD still refuse to make such changes even now, in Q3 2015. Dx11 Dcl

Not true for Nvidia. The frame rate loss is not great, notice the horrible frame spikes though.

permalinkembedsaveparentgive gold[–]companyja 9 points10 points11 points 1 year ago(7 children)CPU Overhead when it relates to the GPU is loosely the amount of additional work your GPU offloads to the CPU that adds further Amd Drivers Source? This thread’s sole responsibility should be to make DirectX calls; any other types of work should be moved onto other threads (including processing memory buffer contents).

basically we blew a buffer right out).However up until that point the MT CL rendering WAS making a significant difference with our CPU time usage and we had near perfect scaling

So the one single CPU core in DX11 that's performing all of your immediate work with the GPU must stop what it's doing and spend time crawling through the DCLs on permalinkembedsaveparentgive gold[–][deleted] 0 points1 point2 points 1 year ago(7 children)But as long as you don't have a really weak CPU, it doesnt matter. permalinkembedsavegive gold[–]TangoSkyR7 1700X | 2x MSI RX480 GamingX 8GB | 144HzFreeSync 2 points3 points4 points 1 year ago(1 child)AMD does support DX11's multithreaded features.

AMD does have a leg up on the lower level API driver development (as they should), but the extra resources from that leg up should be used to add more features You simply replied with "Try it or don't speak".

I really hope AMD will still resolve this and release proper DX11 drivers.

The feature never gained much use -- I think Civilization and Assassin's Creed games were a couple of the few that used them? DX12 by "itself" will not write the AMD drivers code, AMD must do it and do it at LEAST with a similar (if not better) quality and performance than "Vendor A".

For example, if your engine does lots of work in between the API calls that it makes, then it would likely be beneficial to utilize multiple threads which could reduce the I'd say it was pretty important :P - you just don't see people advertise it, because it's a base feature of DX11. Ignoring raw speed, what exactly is the user-visible or dev-visible difference between a GTX 480 and a GTX 980? There's a high degree of submission overhead, meaning it's possible to choke the CPU while submitting a large number of objects to the GPU.

Nvidia's driver used to use other threads to generate command lists when possible then send them to the main thread I think. permalinkembedsavegive gold[–]tr3v1n 17 points18 points19 points 1 year ago(11 children)Also Andrew has a stutter and talks a bit slowly. MS, for all practical purposes, concluded that DX was a mature, stable technology that required only minor work and mostly disbanded the teams involved. For people with lower end CPUs, they recommend the GTX 750 Ti over the R9 270x!

Not sure though. Guest, the last post of this topic is over 60 days old and at this point you may not reply in this topic. It's a huge hit to performance after more than a few minutes of runtime, though DCLs are very lovely at arbitrarily boosting benchmark scores on tests that run for ~30 seconds. Original articles are always better than a reddit textpost.

The situation is even more of an issue on the mainstream enthusiast 1080p section on the next page.
