Did some testing comparisons, Lag can be really subjective. So a way to put an actual number on it is to use the performance tools in Brave (and Chrome). F12, Performance Tab, Start Profiling button. And run it a few times to get a basic average.
Getting around the same load times, Chrome pdf viewer isn’t the quickest but getting the same amount of time in ms. (+/- 500ms). Mac Chrome got basically the same results.
- Check Chrome, is it slow there also (could be just the pdf renderer)
- Test Brave in private window mode, with no extensions
I would keep HW acceleration enabled.
