Is the RX 480 a decent card for unreal engine?

Two things:

  1. Just moving and editing in a large level uses “all the resources” but very chunkily – it’s not 100% load all the time, but frequent spike demands on all of the subsystems. Each upgrade will improve some part of the editing experience. Similarly, the GPU is generally running hard, trying to render all the unoptimized data as well as editor overlays.

  2. Light map baking. This uses as much CPU resources as you can throw at it. Having a bank of additional machines that just help out with render on the network will speed this up …

That makes sense.

So from the two activities you’ve mentioned, I get the impression that they’re things that can still be done with a lower speced card, but would just happen a lot slower?

So you’re not limited in what you can do in the engine, but rather the speed and efficiency in which you do it; so stuff shouldn’t flat out not workbecause you’re GPU, CPU or whatever isn’t physically powerful enough to power the engine (providing of course your system isn’t rediculously underpowered)

Is that right?

Generally that’s correct, however with light map baking if you don’t have enough RAM you may not be able to build your scene at all.

Understood.

Is ram speed a big issue? As said, I’m running 1333mhz sticks. I have 32gb in there at the moment.

Thanks

32 GB should be enough for any scene that indies can build. I baked a bunch of the Epic demos on 16 GB.
RAM speed mainly affects how fast the operations complete, not whether they will complete or not.
So, a 480, with your existing CPU and RAM, will let you do “anything,” assuming you’re patient in certain situations :slight_smile:
And if your game is of suitable indie-self-developer scope, rather than AAA-scope, it’s unlikely you’ll get to the point where the editor bogs down too much anyway.

Since someone mentioned Vulcan it is in development they actually had a demo with it on the galaxy S7. DX12 I can’t find any definite answer for it’s development.

28

Cool. That’s good news, then.

Thanks

I see.

If dx12 and Vulkan are going to be the next big thing, I’d presume dx12 implementation into UE4 would be on the cards at some point.

DX12 and Vulkan will take some more time to be fully implemented into the engine. But if done proper, AMD cards will get a huge gain. They do have a DX11 disadvantage currently which seems to be related to the GCN architecture in general (crearted for multiple tasks while DX11 is simply not made for that; DX12 and Vulkan are).

We will have to wait how epic will implement it. The DX12 wrapper showcased with the Infiltrator demo was extremely disappointing. Performance-wise it was slower then bare DX11. But they also stated that it is not even nearly finished.

Just in case they completely mess up, i do target my current game with 60FPS on a mid-range GPU. Just see what performance average ARK players get and you will get some grey hair instantly…

Interesting information; cheers.
