Maybe I can edit that and put it aside to help in the advancement of an eventual update.
I got me new desktop now so normally there should be no issue with lag due to HQ settings.
but still, some of the disco gun effects look kinda girly and childisch imo (like some codenames or other guns that shoot shiny bubbles), so I rather play with cranked down FX xD
Hey! Im not an expert, but... as an alternative if other solutions not work... maybe you can check the Graphics VideoCard options by right click in desktop, you know... sometimes are options for adjust the 3D settings and compatibilities with older games.
