    Has anyone tested DX12 on Fermi yet with these drivers? DXdiag reported DX12 in the Anniversary update for me but it didn't actually support DX12. It was the same with Ivy Bridge.

    Can't test it myself today.

    A valid question though - do DX12 only games (FH3, Gear4) run on Fermi now? And what kind of performance do they show?

    Please report back if you're seeing better performance

    tested a few things, disabling async compute on time spy improves performance by 20%~, thinking its likely poor optimization thats the reason for the low performance which is not all that surprising,

    performance in dolphin with dx12 using the last build that supports it, yields identical performance to dx11.

    This is also not that surprising in since nvidia has greatly improved their dx11 overhead since the last dx12 driver aswell . i get 1.97million draw calls in dx11mt as well 1.94mil dx12 with the 3dmark api overhead test on 384.76, compared to the 1.3million dx11mt and 1.9mil~ dx12 on the 359.54 early dx12 driver. (the old results were on the same build of windows and the updated version of the api test)

    So, can you guys play Forza 6 Apex now?

    Does this mean that Nvidia finally delivered (despite being late as f)?

    probably, have had no issues running timespy, the dx12 version of dolphin and the old unreal dx12 techdemo, of which unreal and timespy would crash on the old early dx12 drivers

    ill have to give forza a go

    So it's basically useless for the most touted use case of console emulation.

    I guess, does not have an overhead benefit anymore as far as i can tell, not that is matters anyway since no emulators use dx12 afaik (dolphin dx12 was removed) everone seems to be jumping on the vulkan and opengl train to make crossplatform easier.



    EDIT:
    So far forza 6 apex and civ 6 are no go , both require : Tier 2 Resource Binding
    which fermi doesn`t support.

    I've been meaning to recycle this pc for a couple of years, pulled it out of storage and installed win10. Geforce GT 430, 1.6 ghz dual core and 3 gb DDR2

    I will try and get my old GTX 580 up and running again and do some tests. Anything to get away from my AMD frying pan of death for a day or two.

    Really?

    From the review on guru3d.

    This card ran 42 degrees C in IDLE which is very normal. When the GPU is stressed out 100% for several minutes the card reaches roughly 85 to 87 degrees C. For a GeForce GTX 580 these are rather normal numbers. Also, we measure at a room temperature of 21 degrees Celsius.
