What title and screenshot says. A bunch of visual artifacts pop into and off existence when using Pyroland Glasses. I'm currently using the High Preset with a bunch of overrides, also linked in this thread. I'm also using FlawHUD and nothing else.
The only thing noteworthy about my specs is 8GB of RAM (effectively 6GB because goddamn built-in GPUs) and I use a Ryzen 5 2400G with the built-in Vegas 11.
