thx for the info!
short update on my experience with a rtx 2070:
When using Fieldtrip and ParticlesDX11 i have some crashes and very long hang ups while starting help patches. - Sometimes when i add a node like Emitter vvvv will crash - or open several Field Trip help patches it will crash.
Ive had these hangups in shorter forms on a 1070TI but vvvv would always recover, on my 2070 i will need to close vvvv.
I suspected Settings in nvidia Driver to be the problem, i changed these settings and it seems to make vvvv run more stable:
Vsync: Off ( have a 144hz monitor)
Changing these settings appears to help, will update after more testing if this is running stable.
