Rise Of The Tomb Raider PC Patch Adds DX12 Multi-GPU & ASync Compute Support & More

tommybhoy · 8 Jul 2016 at 12:13

This patch includes the following improvements:

Adds DirectX12 Multi-GPU support. Many of you have requested this, so DirectX 12 now supports NVIDIA SLI and AMD CrossFireX configurations.
The benefits of DirectX 12 are still the same, but now you are less likely to be GPU bottlenecked and can reach higher framerates due to the improved CPU utilization DirectX 12 offers.

Adds utilization of DirectX 12 Asynchronous Compute, on AMD GCN 1.1 GPUs and NVIDIA Pascal-based GPUs, for improved GPU performance.

On the latest Windows 10 version, V-sync can now be disabled (Windows Store version), and behavior of disabled V-sync has been improved (Steam version).

No async for Maxwell only Pascal?

I'd be interested to benchmark this in DX12 SLI now.

Hope that IO interactive follow suite and add DX12 MGPU support for the new HITMAN.

I give it 10 posts until this turns into a flame war.

The DX12 multi GPU looks interesting though, especially, how well it works on new cards in the future, but I don't have the game to try it out

No surprise really. Maxwell's capabilities (or lack thereof) in that area are well known. No point enabling it if it's not going to improve performance. It'll be interesting to see which gets the bigger boost out of it between GCN and Pascal though.

If they're using async shaders, then it should be a no brainer that GCN cards will fare better.

What will be interesting is seeing whether or not Pascal can actually improve improve performance in DX12 over DX11 using async shaders, since many thought it couldn't be done and Pascal is just Maxwell with a node shrink.

I'd be interested in what gains both AMD and nVidia get now

Thanks for posting

LoadsaMoney · 8 Jul 2016 at 12:54

Just updated, on Win 7 though, so the Dx12 stuff doesn't matter to me

Mauller · 8 Jul 2016 at 12:54

Would be interesting to see the gains and if the performance is less sporadic now with the apparent CPU overhead reductions and fixes for DX12 in this.

Might download this again give it a try.

I don't know what my dx12 performance was before but running dx12 compared to dx11 now dx12 is worse but not by much.

Saw somebody elsewhere with a GTX1080 say their performance was about the same in DX12 after new patch.

So was Seanspeed an alt account?

seen one nano result. max framerates up 65% in some areas. Min scores down 20% though

thebennyboy · 8 Jul 2016 at 15:38

Some exceptional performance improvements on my 290X.

Before: 78.71FPS

After: 93.57FPS

Improvement: 17.25%

whyscotty · 8 Jul 2016 at 15:40

The gains on the mins are more impressive

SiDeards73 · 8 Jul 2016 at 15:51

You have to ask, seriously, what changed from Console to PC release? and now for them to implement A-Sync to this amount of performance gain? it really does smell of something dodgey...

Poneros · 8 Jul 2016 at 15:56

Nothing dodgy, software development just takes a long time. It's good to see these improvements, it will take the older AMD cards a step above their Nvidia counterparts yet again making them even better value, so I'm happy about that. Will be interesting to see how the 480 does at the start of the next year compared to now - my money is on seeing a lot of improvements but we'll see if it pans out.

LoadsaMoney · 8 Jul 2016 at 16:18

Nvidias Pascals must be good at A-sync then, if they've allowed it to be patched into the game now.

According the patch notes only Pascal from the NVIDIA lines supports it in their game as well. Sucks for Maxwell :/
