I totally get what you mean. GTA 5 Enhanced does run a lot smoother and more optimized but at the moment there is no mods for the new version, I'm not only talking about LSPDFR, I'm talking about all the mods in general. All the mods (the most used and the common ones) aren't available yet. You can make a re-search though, I'm not an expert and maybe you can find something, but I don't think so.
