Zombie Army 4: Dead Wars PC Performance Review and Optimisation Guide

4K Performance - Demanding, but achievable

At 4K, Zombie Island 4 has pushed every graphics card except for Nvidia's RTX 2080 Ti under 60FPS in our in-game test runs, though we would expect Nvidia's RTX 2080 Super to also achieve this feat. 

Lower-end graphics cards like AMD's RX 5700 can achieve 60FPS framerates on 4K screens using a lower resolution scale, with an 80% scale bringing the title to over 60FPS for both average and 99th percentile framerates. 

AMD VS Nvidia

Now we can see AMD's RX 5700 best Nvidia's RTX 2060 by a notable margin, offering a complete reversal from the same situation at 1080p. This highlights how much resolution matters when judging game performance. 

DirectX 12 VS Vulkan

Like before, the general trend is that Nvidia graphics cards prefer Vulkan, especially Nvidia's Turing-powered graphics cards, but on the AMD side we can see that Vulkan only benefits AMD's new RDNA graphics cards.

Happy to see the nonbiased performance in this game. Just 2 modern APIs being used to the best degree possible and showing the barely different performance levels of competing cards.

It's also worth noting how Vulkan appears to be superior. The recent R6 Siege switch to Vulkan with Ubisoft stating better CPU performance, and having this game perform generally better with Vulkan, may actually be the fact that Vulkan is just simply faster right now overall. Plus it's also multi-platform. Seems like a no brainer currently(that is unless you want Ray Tracing).Quote

The Khronos groups have done a great job improving Vulkan's feature set. That said, they need to figure out how to deliver a DXR equivalent. Right now raytracing is only available using Nvidia's extensions with Vulkan. However, I hear that talks are in progress for Microsoft and Khronos to help create a more universal standard, likely by having Khronos use a similar approach to Microsoft.

Khronos has made Vulkan a lot easier to develop for with recent iterations, so it will be interesting to see how things evolve. Right now, DX12 will have an advantage in the near-term if raytracing starts to see wider adoption.Quote

While you aren't wrong, i'd argue RayTracing is less important than raw performance. Ray Tracing is a looooong way from being a standard feature. So i'd take the performance benefit, rather than massive performance penalties for an unequal graphical uplift.

And technically with the wrapper, Vulkan created to help port DX12 code over to Vulkan natively, you could in theory use the RT libraries already. Though I can guarantee it'd be more complicated without the official support to build more off of the ported code.

I don't doubt they are collaborating on a RT library. It's a complicated feature and reducing the effort for developers is key for them using it anyway. Leads to better implementations, shorter development time, and less money spent. Win-Win-Win for everyone. Though again I am definitely glad you are hearing of a collaboration. I would be thrilled for that!Quote

Aye, but I'm talking a 3-4 year timeframe. IIRC, Vulkan 1.2 supports HLSL at up to shader model 6.3, which falls short of DXR. Shader Model 6.3 adds support for DXR.

Vulkan's lack of official raytracing support is why only one Vulkan game supports RTX, and it was delivered very late. Wolfenstein: Youngblood. This could also be a reason why id software decided to drop raytracing for DOOM Eternal, or a contributing factor at the very least.

I think the conversation is gonna change very quickly with regards to raytracing. By the end of this year, two consoles and both AMD and Nvidia will support it.

Another factor that's worth noting is that today's RTX series will always be Nvidia's worst-performing raytracing accelerated graphics cards. Future architectures will enhance raytracing capabilities (which will decrease their performance overhead) and increase their normal shading performance.

I believe that Khronos will discuss Vulkan raytracing at GDC, but it will be a while before it becomes a full part of Vulkan (likely with Vulkan 1.3).Quote
