Fermi support?
Earlier marketing materials stated that Vulkan would be supported on Fermi GPUs. The beta driver page says that Kepler or Maxwell is required. Has Fermi Vulkan support been officially dropped or will it be coming later?

I am curious about that, too. Last time that Fermi support was promised was at SIGGRAPH last August so not that long ago afaik and the API was in a sort of soft freeze already at that point if I remember correctly. Unfortuantely I could not test if there maybe is experimental Fermi support in the current driver, because my Linux distro is too bleeding edge. Downgrading the kernel to the latest supported in the 355 branch would be possible, but I'd also have to downgrade to xorg-server 1.17.

I'm just guessing, but Fermi drivers also still lack D3D12 support and therefore they want to kill 2 birds with one stone with a driver which supports both APIs because of their similarities. But as I said that's just an assumption.

With Vulkan 1.0 the base requirement in terms of hardware features was OpenGL ES 3.1 which is a subset of OpenGL 4.3, which is supported on all Fermi and newer cards.

http://www.geforce.com/hardware/notebook-gpus/geforce-gt-620m has Dx12 support but no Vulkan support.

That would be really great. I have an old 560 Ti and still waiting for the new Pascals. I could continue building my own graphics engine which is somewhat limited with OpenGL yet.

Not too long ago DirectX12 on Fermi was obviously still planned for the end of 2015. http://wccftech.com/fermi-dx12-support/ So maybe there is still hope. Now would be a stupid time to be in the market for a new GPU. The only thing that bugs me about my 580 is that 1.5 GB VRAM is getting pretty close to full with my 1440p monitor that I purchased in the last 5 years. Still has enough horse power for anything I play on Linux. Worst case NVIDIA rolls out the lower end Pascal cards first and we have to wait months and month to replace our Fermi cards with a 1080 Ti.

Just not really an option for me. Nvidia stated Dx 12 and Vulkan support. We need to have it, especially blakout24 said, it is kinda easy to implement Vulkan support to Fermi. We already had an very alpha DX 12 driver long ago. I managed to ran 3Dmark API overhead test in Dx 12 mode, so just don't really see the matter behind all of those delay, what we experience over 6 month now, according to original DX 12 support release date.

+1 for this question. Need to know if driver for my GTX 570 will be provided or if I should wait for an open source driver.

http://vulkan.gpuinfo.org/displayreport.php?id=41 No guarantees though that Fermi will have full Vulkan support in final release drivers.

The oldest cards that AMD supports is the HD7000 series from December 2011. My 580 was launched December 2010, if there is no technical reason I would support them just to be better than AMD. ;) If Vulkan drivers really are so small (PowerVR guys wrote one in a month with 2 guys) and there is no heuristics tuning anymore, because that's the job of the application the maintenance burden of supporting older cards that have all the needed hardware features should be minimal.

[b]+1[/b] I thought every graphics card that supports OpenGL 4.x will support Vulkan. I have a NVidia NVS 5200M in my notebook, with GF117 (also Fermi).

[quote=""]http://vulkan.gpuinfo.org/displayreport.php?id=41 No guarantees though that Fermi will have full Vulkan support in final release drivers.[/quote] According to the developer these entries have been faked. He checked back with NVIDIA and there definitely isn't Fermi support in the driver. However, he says "Es gibt momentan definitiv (noch) keinen Support von Vulkan auf Fermi." which means there is no support (yet). This would imply that he knows more than we do and that support will come. http://www.forum-3dcenter.org/vbulletin/showthread.php?p=10945965#post10945965 Would be nice if NVIDIA could give use a simple yes or no.

Per the Q&A for the Khronos Vulkan webinar ( https://youtu.be/nGkpPp2tGSs?t=2784 ) nVidia is currently not planning on supporting fermi due to an install base issue, not a technical issue. As a long time nVidia supporter and GTX 580 linux user this greatly saddens me as there is not a new video card coming for me for the next several years.
