With the Red Engine 3 though, the game is limited to four threads only, so shader compilation has to be shared with other threads which are already tasked with doing something else. Some game engines that do shader compiling during game time typically are well threaded and so they can use additional CPU cycles to do it without impacting performance. Shaders for example, are compiled in game (which is the number one cause of stuttering) unlike most other engines which do shader compilation during loading screens. The Witcher 3 engine (Red Engine 3) is already prone to stuttering because of how it deals with assets. I conferred with kx11 who was kind enough to test the Witcher 3 on his Samsung 950 Pro, and he said he gets stuttering as well.Īt this point, I'm certain it's just the engine that's causing this problem. I still get micro stuttering when the Witcher 3 is installed on my 960 Pro. At any rate, it wasn't a solution to the problem. My question is, have any other NVMe owners noticed this? Or have I made some mistake with the setup as this is my first NVMe drive?Īnother possibility that I've thought of is that it's possible that since NVMe is a relatively new I/O protocol, the vast majority of games' asset loading is probably still optimized for slower protocols like SATA.Īny help or advice would be much appreciated thanks!Ĭlick to expand.No it's not disabled by default with SSDs, so you have to turn it off manually. So I reinstalled the 850 pro, keeping the same UEFI settings and confirmed that everything was back to normal ie no stuttering. I know it has something to do with the drive, as I still have my old 850 Pro with a full Windows 10 install plus all the games. Batman Arkham Knight is the same thing, though not as bad as the Witcher 3. For instance, Witcher 3 is no longer a smooth game, and the storage access light on my case lights up like a fricking Christmas tree when Geralt is moving, especially in highly populated areas like Novigrad. Regular day to day performance as far as boot up time and loading applications is faster than it's ever been thanks to the new SSD, and my synthetic benchmarks are all in order and appear normal.Īnyway, I've noticed that I'm getting a lot of stuttering in certain games, much more than I was previously. I also have the latest Samsung NVMe drivers, 2.2 installed. Everything went smooth during the installation, and Samsung Magician recognized that my 960 Pro was connected using PCIe 3.0 4x like it's supposed to. I recently bought a Samsung 960 Pro 1TB model to replace my 850 Pro 1TB that I've been using for the past few years.
