I've also seen BIOS settings where it's set to share the 16x lanes, I would double-check that as well.
You could also try putting the BMD in the 8X slot to see if anything changes.
Finally, go through your power settings and make sure it's all set to maximum performance under advanced. is it possible that i don't have the full power of the gfx card because i use all 4 monitors on the card ?

Sometimes its not configurable in BIOS, but there is a description in motherboard manual with pcie configuration when connecting slots. There are times they leave the adjacent to x16 for setups where you need 2x8. Mine for example is 1x16 o 2x8, and then 4x1 I would check that. If you need help, could help if you provice your motherboard exact version

Thank you for sharing this. I checked the Gigabyte Designare 10G motherboard manual. and i do see that when you use some onboard M2 Slots that you could loose some 8x lanes. But i don't see it mention that it would affect the 2x 16x lanes and i only use 1 M2P M2 slot that does not seem to share the PCie Lanes i think.

With info from page 10 and 11 of the manual, I see it depends on the cpu you have installed. Quote:Intel® Core™ X series 48-lane processors:
- 2 x PCI Express x16 slots, running at x16 (PCIEX16_1, PCIEX16_2)
- 2 x PCI Express x16 slots, running at x8 (PCIEX8_1, PCIEX8_2)
* The PCIEX8_1 slot shares bandwidth with the M2M connector. The PCIEX8_1 slot
operates at up to x4 mode when an SSD is installed in the M2M connector.

- 1 x PCI Express x16 slot, running at x4 (PCIEX8_1)
* The PCIEX8_1 slot shares bandwidth with the M2M connector. The PCIEX8_1 slot

(All of the PCI Express slots conform to PCI Express 3.0 standard.) Based on i9-7980XE you said, this is the cpu page and says 44 lanes pcie, so your case is the middle one. Quote:Expansion Slots Intel® Core™ X series 44-lane processors:

Yes thats what I think, that you have to choose between one or the other, not both.
Checking again your first post and page 7, you have a BMD quad 2 or BMD duo 2? AFAIK there is no quad duo 2.
Also if you can share a photo or description on what pcie ports are you using would help. Because in this case is important where do you have the gpu, those 970 nvme and the BMD card... so I can have an idea of the actual bus usages and pcie config.

Because in this case is important where do you have the gpu, those 970 nvme and the BMD card... so I can have an idea of the actual bus usages and pcie config. The first (closest) 16x closest to the CPU is the rtx 2060ti the second slot 8x is empty The 3rd slot (16x) i have the optane card running 3 SSDs 970s so thats 3x 4x slots used on the 16x slot the 4th and last slot 8x slot is the BMD quad 2 (sorry wrongly named) ( i used that slot as it is not shared with any M2 cards. (I only have 1 M2 SSD installed on the closest m2 slot i think M2M and that is not shared with other devices) so it should be safe. I wonder if i remove the M2 wireless card out of that unit if it will help with the resources. I don't need the wifi portion at all.

With manual in hand, PCIE8_1 is disabled when using M2M so its OK. Also I see wifi card shared bus with gigabit, so no problem with gpu/ssds. I cant see a problem in mobo setup, so it has to be the BMD or software related. My experience with BMD in the past was: Good for the price, but not perfect in performance. I would try testing recording without BMD live input... Add a recording from your EVO ssds to vmix and perform a test record of your usual length and check for same frame drops. Also take screenshot of stats panel LIVE vs RECORDED so you can check one to another if there is output dropped frames when using the card vs using a file. This is to know if you should look deep into the BMD or in the system. Hope it helps!

After moving the BMD card to the last slot it was behaving much better only a few drops here and there. I got the Rendering down to about 10-15ms but i am confused why the rendering with a blank setup (no preset loaded) shows a usage of 5-6ms that is extra ms without even using the software.

Maybe the min latency added by card/soft buffers
