I'm a new speedrunner but my laptop isn't very powerful, so the video is a bit laggy.

I'd appreciate any tips to make it less laggy in obs, too.

It may be submitable, DM a mod or ask the fourms of the game.

To make OBS less laggy turn down the cpu preset lower

Connect Laptop to your Router with an Ethernet Cable - I thought it only mattedered for online multiplayer game's but it really helps streams too -

I've submitted tones of laptop (no ethernet) wifi runs, but the quality is atrocious - I think you can get away with it better if you do Super small categories (Like Individual Level things or NES games that might be over in 15 minutes) --- Anything 30 minutes + is bound to have dropped frames on a Wifi-only Laptop stream.
