![]() This included a detailed look at the first asserted reason for the performance gap, the Windows 10 scheduler. Our team has done quite a bit of research and testing on this topic. In that story I detailed our coverage of the Ryzen processor and its gaming performance succinctly: You can combine memory latency with the thread-to-thread communication issue we discussed previously into one overall system level complication: the Zen memory system behaves differently than anything we have seen prior and it currently suffers in a couple of specific areas because of it. As it turns out, the memory latency differences are a significant part of the initial problem for AMD:īecause of this, I think it is fair to claim that some, if not most, of the 1080p gaming performance deficits we have seen with AMD Ryzen processors are a result of this particular memory system intricacy. Most recently I posted a look at the memory latency differences between Ryzen and Intel Core processors. Our team continues to watch the story to see how AMD and game developers work through the issue. An area that AMD has struggled in though has been 1080p gaming – performance in those instances on both Ryzen 7 and 5 processors fell behind comparable Intel parts by (sometimes) significant margins. Both the Ryzen 7 and the Ryzen 5 releases proved to be very competitive with Intel’s dominant CPUs in the market and took significant leads in areas of massive multi-threading and performance per dollar. Not only that, but it does confirm our information that there was slightly MORE to address in the Ryzen+GeForce combinations.ĭespite a couple of growing pains out of the gate, the Ryzen processor launch appears to have been a success for AMD. There you have it, a bit more detail on the software changes made to help adapt the game engine to AMD's Ryzen architecture. Overhead was reduced by packing texture descriptor uploads into larger chunks. ![]() An optimization was identified in texture management that improves the combination of AMD CPU and NVIDIA GPU.By tuning the size of those tasks – breaking some up, allowing multicore CPUs to contribute in more cases, and combining some others, to reduce overheads in the scheduler – the game can more efficiently exploit extra threads on the host CPU. Rise of the Tomb Raider splits rendering tasks to run on different threads.UPDATE (): Crystal Dynamics was able to get back to us with a couple of points on the changes that were made with this patch to affect the performance of AMD Ryzen processors. We are up to two… Rise of the Tomb Raider got a surprise performance update to improve Ryzen CPU frame rates!
