How to diagnose and fix why the fps is so low?

I'm testing this library in Age of Empires 2: Definitive Edition on Ubuntu with Steam.

But no matter which settings I tweak then the most I get is 30 fps whether in the game menus or while playing. How to figure out where the bottleneck is and fix this?

I used these launch options from #5:

DXVK_HUD=full VK_INSTANCE_LAYERS="VK_LAYER_LUNARG_VkGHL" %command%

Please note this layer is deprecated (see #9 ). I'm using libstrangle for a while too.

Just a guess:

• the game have it's own 30FPS cap;
• you have FPS=30 env var set.

FYI I upgraded to a newer NVIDIA graphics driver; 450. This increased the FPS substantially, even up to 100 FPS or so. However, during a game then the FPS very slowly sank to about 4 FPS when it become unplayable :-( There must be a bug or something.

I checked for the env var but it wasn't set. I'm wondering if the game does have cap because I installed Windows 10 Pro dual boot to play and it too runs at 30 FPS... but with all graphic features switched on :-)

So if the game does have its own cap, I'm a little confused at how I managed to get 100 FPS on Linux. And also, somebody I know got a similar but higher FPS on a high end Windows gaming laptop...
