Hi, if you're struggling with FPS, consider using a config, such as Casey's config which is centered around sacrificing graphics to obtain the most FPS. It is a little outdated, but try using it as your autoexec and seeing if it works for you. I use this config with some modifications of my own because my laptop isn't very powerful at all.
