I've been using Sierra Chart successfully on Linux for about 8 months. Up until recently I've only been using the server simulation mode with about 2 chartbooks, each with 3 charts. I did play around a bit with sub instances because I was looking for a way to show two chartbooks at a time. That worked as well, but I went back to a single instance simply because everything was so crammed on my laptop's screen. Since I use NixOS, I install my two instances of Sierra Chart using a custom Nix package. Updates/rollbacks are all handled by said package, such that Sierra Chart is managed by the NixOS package manager as if it were an ordinary Linux-native application :) The only thing I've noticed that doesn't work is OpenGL when using NVIDIA PRIME Offload Rendering (Optimus). My laptop has an AMD Radeon iGPU and a NVIDIA GeForce GTX 1650 dGPU. By default, OpenGL applications use the AMD iGPU. And that works fine with Sierra Chart. But when I try to utilize the NVIDIA dGPU, which requires enabling offload rendering, I get empty/black charts. The issue does seem to be specific to Sierra Chart because I tested a Windows OpenGL demo application with Wine, meaning I used the same Wine OpenGL implementation, and it works with offload rendering. Practically speaking, it's not a big deal because my AMD iGPU can handle Sierra Chart just fine. But I thought I'd mention it.
