In today’s conventional wisdom, that’s correct for most games. As you can see in the chart below, you pretty much top out at a dual-core with Hyper-Threading. That’s a bit of a bummer, but at least it’s better than the results for the same tests using DirectX 11. Adding Hyper-Threading and more cores made no difference.įutureMark’s API overhead feature test seems to top out at fewer cores than we expected. Unfortunately, it hits a wall at about six cores. 3DMark’s feature test shows DirectX 12 scales very nicely as you add Hyper-Threading and and core counts. ![]() This time, with an eight-core rig up and running, the results are far more interesting. Last year, unfortunately, I didn’t have an eight-core chip available and had to settle for quad-core numbers. These are tests of DirectX 12 performance differences between various thread counts and clock speeds on simulated CPUs. T he chart below pretty much proves that cores matter more than clock speed. This was one of the first showcases for all that is possible with DirectX 12, and when I tested it last year I found that a quad-core with Hyper-Threading paid huge dividends over a dual-core. It’s not about gaming but it shows how some workloads will climb for the stars.Ĭinebench R15’s rendering test, though, is a pure CPU test. What about gaming? For that, I first turned to 3DMark’s API overhead test. It doesn’t scale forever, as I discovered when testing the Falcon Northwest Tiki, but here with a “mere” eight cores, it climbs for the stars.Ĭinebench R15 is a 3D rendering benchmark that likes a ton of CPU cores thrown at it. It’s a great real-world benchmark that gives you an idea of how more threads could pay off. first test I ran was Maxon’s Cinebench R15. ![]() You can join the discussion on Codemaster's EGO Engine 4.0 supporting DirectX 12 on the OC3D Forums.Īccording to GDC's schedule Codemaster's EGO Engine 4.0 can already supports DirectX 12. While a lot of DirectX 12's new features have been used, there is no mention of Asynchronous compute being used, so it looks like the EGO Engine 4.0 will not be not making use of full DirectX 12 feature set, though it may just be missing from the description as Intel's integrated Graphics currently do not support it. ![]() An understanding of how to balance CPU and GPU workloads to get the best of modern PC hardware offering improved visuals and more interactive environments. We will also discuss the graphics effects added using the new DX12 features Raster Ordered Views (AVSM and Decal Blending) and Conservative Rasterization (Voxel based ray tracing) adding even greater realism to the F1 world.Īn insight into the main architectural changes needed to move successfully to DX12 and realise a performance benefit together with an understanding of some of the new effects possible with feature level 12 capable hardware. This session will show the enhanced the visuals created using a threaded CPU based particle system without increased the GPU demands and also cover the changes made to the engine while moving from DX11 to DX12. The F1 2015 engine is Codemasters' first to target the eighth generation of consoles and PC's with a new engine architecture designed from scratch to distribute the games workload across many cores making it a great candidate for DX12 and utilise the processing power of high end PC's. The description states the Intel and Codemaster has been working closely in order to optimize the games graphics for their Iris Pro graphics and make use of DirectX 12's features in order to improve performance.Ĭodemasters present a post-mortem on their new rendering engine used for F1 2015 detailing how they balanced the apparently opposing goals optimizing for mainstream processor graphics, high end multi-core and DX12. Codemaster's EGO Engine 4.0 can support DirectX 12Īccording to GDC's schedule Codemaster's EGO Engine 4.0 can already support DirectX 12, hinting that a DirectX 12 update could be coming to F1 2015. ![]()
