I have 1,600 hours in SoD and 300 in YOSE on multiple machines and devices. Recently I installed YOSE on my new 2017 Surface Pro (Windows 10 / i7 / Intel Iris Plus 640 / 8gb RAM / 256gb SSD) and I've been experiencing strange lag I've never seen before. I was hoping since it should theoretically surpass the minimum specs it would run fine, but no matter what spec or resolution I set, the same type of lag occurs in game; it seems to 'slow' every two seconds like something is rendering or loading in the background. I know the Surface Pro isn't the best setup, but I've seen several users of outdated Surface Pros run SoD with no real lag and with consistent 30fps at least, when their Surface has half the processing / GPU power mine has. It doesn't seem like conventional lag; when I'm running for example, it's like I'm going in slow motion every 2 seconds, then normal for 2 seconds, then slow motion for 2 seconds, then normal for 2 seconds, consistently. The FPS remains consistent, but the game world itself slows down. I'm only using about 30% of my available CPU and RAM. I would think it's because it can't handle it, but there is no more additional lag at the highest resolution and highest graphics settings than the lowest resolution and graphics settings, which makes me feel like the problem isn't the hardware. When indoors or moving the camera top-down, it seems to stop. I've tried several mods that optimize minimal specs and disable shadows , SSAO, etc., running in windowed mode, updating Intel graphics drivers, but it makes absolutely no difference. The exact same amount of 'slowing' / lag occurs. It's very strange to me that it'll run at like 60fps while the game world intermittently seems to slow down every couple seconds. Any ideas?
