I'm curious if there are people who don't experience any video stutters, running Simrail.. If so please what kind of system and configuration are you using?
I get quite bothered by random video jerks and stutters and have done EVERYTHING I can think of to identify, quantify, correlate and try to eliminate. To be fair this isn't the only game, but it doesn't happen in every game, or at least it's less noticable in others.
I have a Ryzen 9800X3D, with 7900XT GPU, 64GB low latency DRAM, and a NVME ssd. So it's a pretty good system. I'm running medium-high settings, with minimized LOD, 1/2 textures, and relatively high draw distances. I get from 40 to 120 FPS depending on area. Simrail is definitely CPU limited, and mostly single thread, as many games are. I gathered extensive PC metrics of Frametime generation data, as well as VRAM, CPU and GPU activities, and made graphs and used python scripting to compare all different settings. I can most definitely correlate every stutter to exactly the times when content is being moved into VRAM, so there is some I/O wait. I've optimized my VRAM timings and tuned and optimized CPU per core. I've played with different graphics settings in Simrail, and checked all background activities and driver latencies.. There is literally nothing that makes a change in this and is independent of FPS. I assume it's the game architecture and Unity, and just can't be helped, unless devs optimize better.
Is this happening to everyone? Do people just learn to deal with this?
