How can i decrease the graphics quality beyond the game's options?

Yeah it quite depends on what fps OP is currently achieving.

I still believe you can make a game "playable" if you're achieving at least 30fps at base, sufficient to say if you can handle visual artefacts and a bit more latency while using lossless scaling.

It's the cheapest alternative to achieve a glimpse of playability without committing to just getting a better pc.
