The one built into vs2022 has this and works pretty well if you happen to use it already. I think vscode has many of these features but I haven't tried it there. Otherwise I'd say look at gitkraken (free for personal use I think) or sublime merge if you really want performance.

Personally I use sublime merge or command line for everything. The sublime merge/text interactions are really nice, being able to right click in a diff and have it open the file at the line. You can try them for free forever but the price may be a deterrent since the dark theme for merge is locked behind a license key.
