DX12: 900% FPS Increase Over DX11 - tech
(hx) 01:59 AM CET - Feb,19 2015 - Post a comment / read (5)
Some interesting performance claims are surfacing surrounding Microsoft's upcoming DirectX 12. One such report comes in a tweet from Brad Wardell showing over a 900% improvement over DirectX 11 on an unreleased GPU playing an unspecified game. The Stardock boss tweeted:
Did a test of DirectX 11 vs. DirectX 12 on an unreleased GPU with an 8core CPU. DX11: 13fps, DX12: 120fps. Lighting and lens effects.

Oh ok, 900% faster using something and playing something. Great. I'm sold. :roll: Is this really news...?

I call bullshit. DirectX (Direct Extensions) was supposed to give you direct access to the GPU features with as little in the way as possible. DirectX has added more and more bloat with every new revision and you don't make something faster by adding more bloat. This is nothing more than hype to get you to buy Windows 8/10 as they won't be releasing DX12 for Windows 7 for, err, reasons.

I still have fond memories of being told games were not compatible with Windows 2000 and I would have to buy XP to play them. Install Orca, remove the check and the games ran fine.

Ok folks, calm down.

See, if you have a game that requires full DX12 to play it and you have two cards that have identical specs with one difference: one supports DX12 another doesn't, FPS gain is literately infinite on a DX12 capable card! :D:D:D:D:D

on a serious note, the scenario here is using dx11 you have 2-3 fps due to cpu overhead, another instance is using dx12 and has 60fps because it doesn't suffer from CPU overhead clutter. They already showed us that DX12 is reducing the number of operations required from CPU and spreading the remaining load equally over all cores. DX11 is old, it was made when dual core was "wow" and updated when it was mainstream so naturally DX12 will address the issues around multi-core CPUs that they didn't have to deal with before.

It's like what mantle does on AMD GPUs, where supported, but better.

The math nerds over at another site corrected this: it was supposedly a 820% increase, not 920%. Although I find the difference is not worth everyone going postal over, if the numbers hold even close to true. :lol:

The tweet is specifically lightning and lens effects related.
I'm sure you're full of bile over lots of things, but this isn't even microsoft, but a developer. why would you have a spergout over that?
