Yeah hopefully they'll support it with more upto date drivers on GTX cards since they're still so widely used. RTX Voice, from the demo's I've seen/heard is pretty amazing. Like, they way it extracts your voice from loud environment/s. Discords own built in one one works quite well (for me) too but I'm assuming dedicated hardware will be a lot better.
Only issue is that its quite GPU intensive meaning it might impact performance quite a bit on older cards. Still, a nice option to have is better than none!
