You could use the Nvidia control panel to check your GPU clock speed and utilization. Despite having that titan, you still could be asking too much of it. Looking at your above screenshot, it doesn't look like you have much of a bottleneck that I can see. If you want a more in-depth look that task manager can't give, use Windows Resource Monitor and select your vintage story process. You have good hardware and it's not being maxed out so I doubt resmon will tell you anything very useful. It probably is just a "game optimization" issue. I put that in quotes because you are definitely playing on the upper limit of what the game can even render and give you. I did notice some FPS improvements on the 1.20 RC releases so perhaps you might see that boost as well (whatever that may look like). If you want to see where your FPS dips and what causes it in game, you're gonna have to have the fps debug menu open and play around with the settings and by playing with the settings, you can find your bottleneck. Not that there really would be much you could do until there was an update to the game. Make sure to be playing in full screen exclusive as well. Full screen borderless will give you less frames generally. That's about the only "general" setting you could have that would work against you in terms of getting the most FPS.
