Lightroom sliders etc slow to respond

Using Windows 11 and have an AMD Radian 5700XT Graphics Card also 32gb of RAM.

When i start up and use LC all is good for a while then everything starts to slow down, sliders slow to respond, also remove tool circle moves but does not follow on for a few seconds.

Reinstalled LRC and tried changing preferences etc but still no joy.

Cleared cache and optomized catalogue.

Updates all installed.

Hi @Allan30656907meg7,

Thanks for reaching out. Before you spend money on a new graphics card, let’s check a couple of things first.

Your AMD Radeon RX 5700 XT was released in July 2019, so it’s now over seven years old. It was a mid-to-high-end desktop GPU at the time, with 8 GB of dedicated VRAM. While newer Lightroom Classic features can place greater demands on the GPU, I wouldn’t rule out other causes just because of the card’s age.

Since Lightroom Classic initially runs fine and only becomes sluggish after you’ve been editing for a while, I’d like to check whether something changes during the session.

Could you please share your System Info when the slowdown occurs?

In Lightroom Classic, go to Help > System Info > Copy, then paste the information into your reply here.

That will help us check your Lightroom Classic version, graphics driver, GPU configuration, and memory usage for anything that might explain the slowdown.

Also, could you take a look at these two reports and let me know whether either resembles what you’re experiencing?

I’m not suggesting these are necessarily the same issue, but comparing the behavior may help us narrow things down.

Let’s check the System Info before concluding that you need a new GPU.

Best,
Anshul Saini

Thank you, looks like I have to replace my graphics card, more expense 🤣

Have you check that you’re using the latest driver for GPU?

> all is good for a while then everything starts to slow down, sliders slow to respond, also remove tool circle moves but does not follow on for a few seconds.

The symptoms you describe often occur when LrC has used all of the GPU memory. I believe the 5700XT (circa 2019) was supplied with 8GB of ram, which is the minimum for Windows 11 The recommended amount 16GB

I did not know the GPU had memory but my main memory on computer is 31gb of ram.

There’s 8GB of ram on your 5700XT that’s dedicated to any operations carried out by the graphics card. With LrC that’s almost everything these days. When using Windows 10/11 the 32GB of ram you mention isn’t used by the graphics card.

As I mentioned above, the minimum amount of vram required by LrC is 8GB, but recommended is 16GB.
