JUST got a Fury to hold me over til Nvidia cards came down in price or til i found an AMD card i was comfortable with. go to run Port Royal and a) guess i need to install the scary Win 10 1809. b) it says i don't have enough VRAM.

anyone out there with 4GB able to run it at the default benchmark res and/or at least 720p or 1080p?

Your card doesn't met minimum system requirements


You won't be able to run it

It's a raytracing benchmark anyway, and your GPU doesn't support raytracing.

dang, where did you see that? i looked AFTER i purchased it on the steam page but didn't see any requirements

Futuremark is doing vendor agnostic raytracing. RTX just has acceleration for specific aspects of raytracing. older dx12 hardware should just do it the hard way

From what I remember when they first announced the benchmark, the first version only supports RTX enabled cards. I think later versions should add support for non-RTX cards.

Any DX12 GPU can do ray tracing. RTX cards just have extra hardware to do it a bit faster.

Do AMD Drivers support DXR?

At the launch of Port Royal, the only graphics cards with drivers that support Microsoft DirectX Raytracing are the NVIDIA GeForce RTX series, Quadro RTX series, and the NVIDIA TITAN RTX and TITAN V. More cards are expected to get DirectX Raytracing support in 2019.

ah, i guess that's the kicker. there's no good translation of an exchange, but from what i saw, there's no plans for the DXR in AMD drivers until all cards can support it.

yeah. raytracing definitely can be done in DX (the executable in the video linked was released in 2008), just not on AMD with what 3DMark is currently requiring.

it's a bummer there's no fallback to bruteforce the raytracing at a (big) penalty.

Anandtech said:
At the base level, DXR will have a full fallback layer for working on existing DirectX 12 hardware. As Microsoft’s announcement is aimed at software developers, they’re pitching the fallback layer as a way for developers to get started today on using DXR. It’s not the fastest option, but it lets developers immediately try out the API and begin writing software to take advantage of it while everyone waits for newer hardware to become more prevalent. However the fallback layer is not limited to just developers – it’s also a catch-all to ensure that all DirectX 12 hardware can support ray tracing – and talking with hardware developers it sounds like some game studios may try to include DXR-driven effects as soon as late this year, if only as an early technical showcase to demonstrate what DXR can do.


In the case of hitting the fallback layer, DXR will be executed via DirectCompute compute shaders, which are already supported on all DX12 GPUs. On the whole GPUs are not great at ray tracing, but they’re not half-bad either. As GPUs have become more flexible they’ve become easier to map to ray tracing, and there are already a number of professional solutions that can use GPU farms for ray tracing. Faster still, of course, is mixing that with optimized hardware paths, and this is where hardware acceleration comes in.

But 3DMark Port Royal requires video card drivers that support DXR, so I guess it will just refuse to run?

probably. i just got a refund until AMD rolls it out on drivers or unless i get an RTX *spit*
