50i or p project: set your monitors at 50 hz.Īnother thing to do is to disable stuff like c and p states in your bios, and let all clocks (gpu, cpu) run at a constant speed. I think it's important to follow the excellent optimisation guidelines posted by Martin on the website, and also indeed to make sure all screens are in the same resolution as your vmix project. I've just finished 3 top notch x299 builds and also see some more spiking in render times than usual, compared to z270 or z370 builds. I've been building several (15 or so) systems over the last years, and x99 was the worst. Thanks for all the support and creative suggestions! Holding my thumbs that this system is now good to go after some further burn in tests. Might be caused by the scalers and splitters I used to fix seven sources with only two cameras. A few framedrops, but I can live with those. Render times looked stable and good between 6 and 10 ms, and the total CPU never above 30% (overclocked to 4,4 Ghz). Upfter updating vMix to 17.107 I did some brief tests using seven inputs at 1080p, streaming (FFMPEG, hardware) and recording (mp4, hardware) - all att Full HD. But I can't get the Intensity pro to function, no matter how I shuffle the cards between the slots. It now works with 1 Yuan SC542N4-HDMI and one SC542N4-SDI. Lo and behold, that seems to complete all the tricks. Then I installed Windows' Anniversary update. Installed them, and if I remember correctly it helped a little bit - but not all the way. To begin with I have had a really nice vacation :)īack in the studio I found that Asus had updates for the chipset, MEI, Audio, and Asmedia. now i can hook this up to my local wifi and i can make a local broadcast so my cameramen can watch what i am doing or my clients can watch what i record in another room. Ps i also bought a yuan intranet server box: small, flexible and very reliable and cost effective. to avoid an conflict.īut then i am still working on my trusted amd a10 system with integrated gpu and only 3 inputs and a desktop capture. remove everything install the driver and the put the card in place. If i want to absolutely safe i uninstall the cards. this also might cause trouble, i alwas have the card drivers instal files on the system so i can quickly uninstall and reinstall after an update. i really hate that, but seems to be unavoidable. On top of that windows 10 is updating all the time. the bm cards are picky: i have two discrete lanes but can not swap, it only works in a specific config woth the yuan. I use the yuan in combo with bm mini rec or monitor. they perform very well, not a dropped frame over long recording times, cooler, only pcie *1 I recently bought a number of new cards 2 sdi low frame, a new hardware type layout. i found out the problem was that i had installed the new drivers but this did not remove the old driver. I v had some discussions with them regarding observed spikes in render time and dropped frames. If you are using yuan cards be aware of the following: And I have yet to test with more capture cards, and their PCIe slot allocation. Still get a slight stuttering when Fullscreen is on, but not as bad as before (render time still sub 10 ms, and total CPU sub 30%). But it would of course be nice to know why it sometimes seems to spin too low for vMix. For sure, I can setup my PC to always start GPU Tweak with Always 3D clock. But by using Always 3D clock it seems OK render time wise.įor the moment I am pretty conviced that there is an issue around how the GPU clock is controlled. The PC with the 970 also has three monitors attached, so that's probably why it's GPU clocked is always on 899.Īs I added a Yuan SC542N4-SDI capture card (started with one Yuan SC542N4-HDMI), and attached a few cameras I noticed that 900 was not sufficient. A little later, while experimenting with different things, I found that if I had three monitors attached to the X99/GTX980 (earlier I had only two) the clock spinned at 900 hundred something (without selecting "Always 3D clock"). Not sure what it does, except getting the clock to spin at a steady 1300 something. Maybe I was onto someting.īack to the X99 machine and I selected "Always 3D clock" in GPU Tweak. So, I installed GPU Tweak on another workhorse with a GTX970. Initially it starts at around 230, but on and off spiked up into the 800-1000 range. In it I noticed that the GPU clock spiked. But that seems not to be the main problem.Īfter spending *many* hours on this problem I tried installing Asus GPU Tweak II. I've tried moving around the cards, including the Nvidia, between slots.
