Street Fighter 5 cannot run in low spec mode from Razer Cortex?

Hi, i’m trying to play SF5 running from Cortex, but it will always run it in normal mode. SF5 is one of those Steam games that gives you launch options when you run it (Play SF5 - Play SF5 in low spec mode).

Cortex only runs it in normal, i need to be able to always run it on low spec mode since that’s the only way i can play it smoothly.

Any help to fix this please? Help!

Thanks in advance!
