No Newer CUDA driver is available... Update Required

No Newer CUDA driver is available... What's happening?


Yet it says "Update required". Clicking on the "i", I get this...


What else?
CUDA Driver Version: 410.130
GPU Driver Version: 355.11.11.10.10.143

Clicking on "CUDA Driver Info & Updates" does nothing.

Checking my System Information, I see this...


What? Intel Iris Pro 1536 MB for Graphics? Why is the NVIDIA CUDA GPU not being utilized on my MacBook Pro?

Going deeper into the System Report, I get this...

November 2019... "Nvidia is to drop support for macOS in CUDA..." - http://www.cgchannel.com/2019/11/nvidia-drops-macos-support-for-cuda/

  • the last update is version 10.2
  • the latest Apples support AMD
How to check GPU on MacBook pro? 

Find out which graphics processor is in use on your MacBook Pro... https://support.apple.com/en-us/HT202053

Based on the information, I have to open an app that uses GPU.

So I opened Final Cut Pro X.

Lo and behold! It's there...


Now I see NVIDIA GeForce GT 750M 2 GB!

Then I opened OBS.

Checked the Activity Monitor Energy usage...


Yes, both OBS and FCPX are using the High-Performance GPU.

"To see if an app is using the higher-performance discrete GPU, open Activity Monitor and click the Energy tab. If you don't see the Requires High Perf GPU column, your computer only has one graphics processor. " - https://support.apple.com/en-us/HT202053

This whole thing is to check whether OBS live streaming latency issues with external cameras are actually caused by the GPU not being detected.

So the conclusion is... The GPU is working fine.

On with the next investigation before investing in an Ecamm Live app, or a new gaming Windows laptop... or a new MacBook Pro.


If Ecamm Live can distribute the processing workload between the CPU and GPU, is there a way to make OBS do the same thing?

Macbook Air M1 Case

I bought a transparent case for my MacBook Air M1 . It came with a free screen protector, a keyboard cover, and some rubber plugs to cover the ports. Check it out! https://youtu.be/d-wALSd3nn8 I didn't expect the rubber plugs. It was a nice surprise. The case fits snuggly, with access to all the ports. The keyboard cover is almost invisible to the eye. I have no intention to use the screen protector. Why? I need to see the true color of the display for my YouTube videos. ~ Adrian Lee  @Adrian Video Image  The video was recorded on iPhone 12 Pro Max with Filmic Pro app in 4K 60fps and edited with Capcut.

Sony Vegas Pro 8 Tutorial - Multicamera Editing

Sony Vegas Pro 8 makes it easier to edit videos from different cameras right from the timeline. You can capture and edit video for a single scene from 2 or more cameras or for a single scene shot a few times with one camera. Here is a tutorial of a Multicamera Edit of a drama I shot. The drama was acted out four times to the public and being a non-profit organization, the client have budget only for one videographer. For each of the 4 acts, the camcorder (Sony HDR-FX7 High Definition Camcorder) was placed at 4 different positions and shot in various angles. Multicamera edit is accomplished in only 8 steps with the Sony Vegas Pro 8. Step #1: Capture Multicamera Video Clips Use the normal Sony Vegas Video Capture function to capture recordings from each camera. Give each capture filename a unique name. Enable scene detection before capturing so that each segment is captured as a separate clip. Step #2 : Layout Video Clips on Timeline Drag and drop video clips over each other on the...

FCPX - The storage device "Macintosh HD" is almost full

The message "The storage device Macintosh HD is almost full" appeared when I was editing a video with Final Cut Pro X on my new Apple Macbook Air M1.   Final Cut Pro Taking up Too Much Space  My Macbook Air M1 had only 256GB of storage onboard. My raw footage was only about 9GB. The biggest file was the FCPX project files itself at about 140GB! How did 9GB become 140GB? There is not enough disk space for my Final Cut Pro. Why Is Final Cut Pro Taking up So Much Storage Final Cut Pro renders files in high-quality media so that we can playback our edits smoothly direct from the timeline.  It creates multiple HUGE high-quality files of our footage in the background.   It is a good thing, so as to maintain high-quality final edited video, BUT not a good thing for a laptop with only 256GB. How to Clear Disk Space on Final Cut Pro The question is how to delete the rendered files in FCPX? 1. Select the library in FCPX...  2. Go to Files > Delete Generated L...
