Jedi Survivor is definitely one of the games on my radar, and yes, it looks like the patching has improved it's performance and polish considerably.
Here's a clip showing it being played on the 9/5 patch 7 on a RX6800 and 12900K, which is only roughly 4% more powerful than your 7700X. BTW, patch 7.5 that released 10/10 only includes a few polish tweaks that are not performance related.
This video shows it played at 1440p, but settings are maxed, so the average FPS is closer to 60. As you can see though even when it's averaging 55 FPS, there's not a hint of lag or stutter. It might come down to what refresh rate your display is, but anything that does well at 60Hz should be good on your spec.
As you can see at the 5:48 mark this build still has animation issues, which is part of what patch 7.5 fixes. So, while it looks like now is a good time to buy as far as the condition of the game, it's still going for $70 on Origin, Steam, and Epic for just the base game. You may or may not be able to hit a Black Friday sale on it if you wait a week or so. It is however included in the EA PlayPro subscription for $15 a month. PlayPro is a no contract service with no penalty for cancelling at any time, so you could play it for a month for $15.
