DX12 broken on games

Patrickman · 16 Mar 2016 at 23:10

Hi Guys.

I have 2x 980ti's and appears DX12 is broken on games like Rise of Tomb Raider and the new Hitman game

It appears enabling DX12 and having SLI doesnt play nicely with Rise of Tomb Raider and crashes the minute you get the first screen

Hitman game with DX12 enable crashes after 2-3 minutes of game play

Do you think its devs not optimising DX12 correctly or the GPU drivers issue?

Does dx12 support sli? I supports multi gpu but does it do that with nvidias sli or some other structure.
Andi.

Multi-GPU isn't broken in any DX12 games, it's just not been implemented. Multi-GPU in DX12 requires the developer to implement it into the game engine.

Sorry OP DX12 having been toted as the saviour of MultiGPU by NVidia and AMD is actually going to be it's death. The onus moves from the GPU manufacturers to implement in driver to the Game Devs to implement in game engine. Virtually no game dev is going to waste time and money delaying a release to do that for a tiny market segment.

If the next gen of consoles go down the multiGPU route things may change but the likelihood of Sony and Microsoft doing that is somewhere between zero and none.

We were discussing it here

Having said that, DX12 does work fine in Hitman EXCEPT on the first training mission where it always crashed for me, usually around the ramp in to the 'boat'

And as for Tomb Raider, it didn't crash for me but SLI doesn't work in DX12.

It's going to be a while before we see engines that are built ground up to support DX12 effectively....probably take a couple of years.

I believe your not thinking ahead.

GPU chips are harder to make small & powerful now days, we are now at a tipping point same as CPU a few years back were its cheaper & better for Multi-core GPU design.

So few years down the line we will have a single card with 2-6 small AMD GPU built into the board.

DX12 is the first step it teaching developers to use MUlti-GPU ready for when this occurs.

2016-17 - Multi-GPU wont be cared as much for due to costs,

2019 - Multi GPU will be a "thing" thats needed for performance to be good enough.
Consoles will also go this way helping developer support

AMD have already stated in a pcper interview MultiGPU is the way forward.

I don't think multi-GPU is really the future. Not when things are becoming smaller and more "integrated". Plus cost will always keep it out of the mainstream.

Your thinking of it wrong. Your thinking if it as Multiple GPUs.

Imagine a board with 6 tiny GPUs that can work as one or or 6 GPUs in one die.

Think if it as multigpu-core threads

You can no longer buy single core CPUs. The same future for gpu's

They cannot continue making faster smaller dies eventually you will need more smaller dies

Then you will see quad core CPU with built in dual gpu

The problem with that is that game requirements will require "GPU with x number of cores"...

A segregated market will become even MORE segregated.

Requirements will continue to be based on 'ATI XXX or nVidia YYY' or similar...multi gpu doesn't change anything.

Multi-gpu is the future, no doubt about it. It'll just take time for adoption. It's not easy...

MultiGPUs supplied in this way would require the work to be done by the manufacturer prior to it being done by the OS dev or game dev, it'd be more of a collaboration than currently where SLI/Crossfire is more or less dumped on the game dev to sort out with minimal support elsewhere. I used Crossfire for several years, moved to SLI then simply gave up with it, great idea but until the industry across all three sectors (OS/Game/GPU Manf) sort their stuff out I'm not interested.

thats the thing its, its already happening,

Soon as AMD/Nvidia release a MulticoreGPU will see OS/Dev development.

it will happen & become a standard for any Computer in the future, They will do it NVIDIA GRID could benefit a lot from MUltiGPU Core support

the same as running multile ARM Cpu iin servers

it qwill take time but it will be a part of the OS going forward
