Laging in preview-mode even with 4K Computer!

[Aaron Star]

Read the expansion slots section in the manual, page 8. Clearly you need to keep the M2 enabled. The GPU needs to go in a non shared full bandwidth slot. The slots are marked on the board. The devil is in the details of the ** notes. The diagram on page 1-13 and 1-14 could help as well.

Due to the way they have implemented the M2, that slot shares bandwidth/pci lanes on the cpu side. You need to determine the slot that maintains full bandwidth when things like the M2 and USB 3. Supposedly slot pci16_1 one does this, but there is still something that is not right.

In bios look for advanced, then check the following:

DMI – gen 2.0 should be disabled.

NB PCIE Configuration – pcie16_1 should be Gen3, not auto. Per documentation on page 3-38. Auto for other pcie slots on the board.

I do not believe the x16 issue will solve all playback performance issues, especially if you drop a compute heavy plugins on a clip. For optimization reasons, you want to max the bandwidth from the memory/cpu to the gpu memory/gpu for the best opencl performance and playback.

DMI – gen 2.0 should be disabled.
-DMI gen 2.0 was enabled I switched it to disabled.

NB PCIE Configuration – pcie16_1 should be Gen3, not auto.
-pcie16_1 was on auto I switched it to Gen3.

But still nothing changed.
GPU-Z still shows the same thing.

Omg! This is really really weird … haha Finally!
Look at this! I changed the slot to one below and it got recognized in the BIOS.

Afterwards I went to Win 7 installed the latest driver for it but I still had not the full performance.

I put the graphic card back to the first slot and it got recognized!
I checked GPU-Z and these are the results. 🙂

But still having my stupid lag issue. =(
At least I’m having a good mind that I don’t have any hardware-problems.
Well I think so … but maybe my CPU has some problems !?

GoPro as far as I know just records in h.264 at 60Mbs. I would think your system would decode even that high of a bitrate just fine. I would try using vegas to convert the gopro original file to Cinform.avi, HDCAM-SR-Lite.MXF, XDCAM-EX.MXF, or XAVC-intra.MXF. Try the playback of one of those formats and let us know if the playback is better.

Since the Vegas render profiles are dated, you will need to create your own 60P profiles by changing the Frame rate to 59.94.

Wow I can’t believe it! Seriously FINALLY!
It took so long to solve this Problem.
I never knew, that there are effects that are based on CPU and effects that are based on GPU.
I was using effects for the CPU all the time. That’s why I coudln’t see huge differences compared to my old computer.
It’s still weird why It reaches almost 100% but since I noticed this Folder:

I can put tons of effects in the video and it doesn’t lag.

Thank you so much Aaron & Wayne for your help!!!
Thank you for all these information! And I also solved my graphic-card PCIexpress 16 v.3.0 problem with your help!

But I sitll have a question.
What should I do if I want to use 2 different video-files at the same time?
For example a gopro 1080P 60 frames video and a 4K 24 frames Video.
Because of the different frames and different sony vegas settings it starts lagging again.
Any Ideas?

Glad that your system is finally up and running.

I’m not surprised that you are still experiencing preview lags with those disparate frame sizes and frame rates within the same project. My suggestion is to create proxies based on your final render settings. E.g. if your finally delivery is 1080 24P, then create a proxy with those settings for both types of footage using one of the formats suggested by Aaron. Your preview performance will now be the same, and you can revert back to the original footage for final render.
