Ask GN 33: Hyperthreading & Games, Dx12 Performance

Posted on November 8, 2016

Episode 33 of Ask GN answers a few more questions than we normally take, resulting in a 20-minute run-time for the episode. We talk about hyperthreading and its impact in some specific games, DirectX 12 performance, scaling of Dx11 and Dx12 performance on AMD and nVidia GPUs, Furmark, and a few more topics. One of those other topics was on recording software's impact on framerate, like Shadowplay, OBS, FRAPS, or GVR.

You can find the embedded Q&A video below. We've been running these for a bit more than a year now, making Ask GN our longest-running series by a longshot. As for content this week, because we often take Ask GN articles as an opportunity to discuss what's coming, keep an eye out for more EVGA VRM updates, BF1's performance with various RAM speeds, and a couple smaller items.

1:05 - Comanso Rowlett: "Is there a need for Hyperthreading on 10 core CPU's like the 6950X if you're going to use them for gaming? Or can you disable it, to gain a more stable overclock if needed??"

4:30 - dirtzoo: "this is a question for the AMD expert cat. I built a red machine for BF1. FX9370. GIGABYTE FXUD3 rev.4mobo. two XFX RX480 1333hrz gpu's in crossfire. Direct X 12 does not seem to support crossfire in this game. I tried Direct x11. but is unplayable with tearing and ..just bad things happen in crossfire. do you think Direct X 12 will support crossfire in the future or is there another way to get it to work to get my fps up to manage free sync with my 144hz monitor.?? I am getting 90-ish now on ultra with one monitor. but if I use two it stutters bad. lower settings or resolution dies not seem to help. 850w gold PSU. 16gs of DDR 3 . it is not a power issue is it? I am stumped. please help AMD cat!?"

9:00 - John Smith: "Coming from one of your CPU review videos, I have a question: could you add a gaming+recording scenario as one of your CPU and GPU benchmarks? The reason I ask is because there are more and more gamers recording their gameplay, but PCs take a hit in performance when doing that, and it would be nice to see how much of a hit can be expected on a processor or graphics cards under those circunstances."

11:58 - Surpuppa: "For the next Ask GN: WHy is it that AMD has a larger performance gain on DX12 than Nvidia? This is for the new and old cards. Will this be the same going forward? (Vega vs Volta)?"

16:20 - Tuchulu: "Do you use Furmark??"

16:32 - Peter Kostov: "Steve, you mentioned that it is possible to move workload from the CPU to GPU, what possibilities are out there to do that? I have a FX-8350 which is really bottlenecking my bf1 (I get same fps no matter what resolution I play, so that obviosly my GPU can handle a bit more workload). So I want to use this shift as an interim solution until Zen comes out."

17:55 - 12345ApplejuiceBum: "Hey Gamers Nexus, what is the theoretical minimum size that a GPU die set could be manufactured too, before electrical resistance halts the shrinking process? Also what is the naughtiest thing the cat has done while you were trying to film??"
