I have done some rudimentary testing, and I have concluded that VS Code does not render above 60 frames per second. I recently enabled smooth selection caret rendering, and I noticed that for moving to the end of longer lines, the number of frames rendered are about half or less than what is rendered by my mouse going at the same distance and speed. I have a 144hz monitor, and 144 is more than double 60, which would confirm my test results.

Additionally, I can get 144 frames per second in Chrome, tested via https://www.testufo.com/ and compared with Firefox running at 60 frames per second.

What I would like is the possibility of rendering VS Code at a frame rate higher than 60. This would of course only be expected with GPU rendering.

For what it's worth:
https://github.com/microsoft/vscode/blob/da0afcff64ff1efc6ae6580294537b3b87dd682e/src/vs/base/browser/dom.ts#L430

Changing it to 6 (144 FPS is 6.9ms) allows for 144 FPS mouse-based scrolling (dragging scrollbar). It does not appear to change monaco css animations (for smooth cursor caret).

I for one would really like to see VS Code respect refresh rates higher than 60hz. I cringe whenever I need to switch over to VS Code from PhpStorm on my 144hz monitor.

I'd even be happy with 100 FPS if it's a performance issue. Or allow the FPS cap to be configured for "power" users. Or use requestAnimationFrame() like it's not the 20th century. Or something!

If you're still looking for a solution, adding these settings to settings.json should do the trick.

  "editor.smoothScrolling": true,
  "editor.cursorSmoothCaretAnimation": true,
  "workbench.list.smoothScrolling": true,

im a starter user, how i can get at vscode/src/vs/base/browser/dom.ts, ive searched this path and i cant find

@LukGaming I assume you would need to clone the repo, make that modification, and build VSCode from scratch. It's more of a POC than a solution.
