Glad to hear that! Two days stable is a great sign. You’re probably right about the shader cache NVIDIA’s default is often way too small for games like VoTV that keep adding new objects as you progress.
And yeah, definitely a smart move to stay away from the BIOS flash while under the influence that’s a 'sober self' task for sure. If it starts acting up again around day 30-40 when the game gets even heavier, that 2023 BIOS might be the final boss you'll have to tackle (a lot of USB stability fixes for X3D chips dropped in 2024/2025).
For now, just enjoy the game and stay safe out there in the woods!
