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

I have a similar system and noticed the same type things! I thought it might have to do with the drivers and RTX 3090 being just a little too bleeding edge to be fully taken advantage of so ended up switching to an RTX 5000.
I would also like to hear a bit more about what the high output performance actually does and why would we not want to use it?

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.

We are still using this today and I’ve got no idea what it does but it keeps our performance solid.
I’d like to turn it off but have no idea if it’s stable
Enough yet I assume so after all this time.
Anyone still
Using 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.

"High Output Performance" only shows when you pass the "Only use these if you're told to" gatekeeper.
It may be there because allowing that performance increase puts undue pressure on the performance of other critical subsystems in vMix. It may be older supported systems running vMix can't handle that option and they don't want to default to it until those systems are dropped from support while most newer machines can handle it easily.
What we really need is a clarification from the people who really DO know what the true effect of that option is and I am definitely not the person who can tell you. I'm keeping it turned off in my copy for now because I'm going to assume that it's an unsupported configuration until I hear otherwise.
