Hi All,

I was wondering if anyone had any knowledge of the High Output Performance Mode in the Advanced setting of the performance tab?

I've recently been battling to bring my render times down on my new rig.

Intel i9 10980XE
Nvidia RTX 3090
Asus Strix X299 Gaming II Motherboard
64GB Ram
1TB M2 drive
4TB SSD

I've disabled onboard sound, disabled CPU speed step in the BIOS etc. I've checked for dodgy drivers with latencymon and also made sure all PCIE cards are in the correct busses. Even then I seem to often get render spikes before I would normally on a lesser system.

I'm aware of the High INPUT performance mode, however yesterday I stumbled across the High OUTPUT Performance mode setting in the advanced menu. I was sceptical to switch it on however when activated it dropped my render time by up to 5-10ms straight away. I can't seem to find any information about this setting in any vMix guide and I can't find much discussion about it.

My question is; What does it do and if its in the advanced menu, which I don't generally touch, what's the catch!? It seems to improve performance on my system fairly dramatically but is it reliable for shows?

I'd appreciate anyones knowledge on this! Thanks in advance

We use High Output Performance Mode on everything. I believe it's meant to help with 4K projects, but we've see significant improvements with our 1080p5994 projects.

We use it along with the new Resizable Memory Bar Support wherever possible, too. We do have high input performance mode turned off in this case, per the VMix.com instructions, but still keep Output on. In our testing, we still see better render times with it on, although to be fair that testing wasn't significant. I'm not sure if that's the behavior we should be seeing.

If you aren't doing Resizable Memory Bar Support, I highly recommend it. Dramatic improvement for us. Your mobo, cpu, and gpu combo def support it.

I have an old gpu Gigabyte gtx 1070ti 8gb and im running 1080 50i. I see that with enabled high output perfomance mode and when i enable the external out-->bmd intensity pro 4k-->1080 50i the render time is 3-4ms. With the high output mode perfomance disabled the render times is 8-9ms.
