Question

Lightroom Classic 11.5 slow when selecting subject.

Full disclosure: I'm a complete newbie to Lightroom. 

 

After a few days trying Lightroom "CC", I've tried switching to Lightroom Classic as it has more features and most of the online tutorials show how to do things in Classic. Everything seems to be ok... except for anything dealing with AI masks. Select Subject, Select Sky, and any subject/sky adaptive presets all take 3 minutes or more to work. Detecting..... Working...... Refining...... but when it's (eventually) done everything works fast from there. 

 

My laptop is less than a year old and has minimal software installed. i7, 12MB RAM, Intel XE graphics. It's not top-of-the-line, but it should certainly be up to the task. All other aspects of Lightroom run quickly. I've updated the GPU driver (clean install) to the newest version available directly from Intel. I see in the forums I'm not the only person running in to this or similar issues. 

 

I really want to get proficient in LR Classic, but this issue is making it almost unusable.

In LrC, click on Help, click on System Information, look at this section:

Displays: 1) 2560x1440
Input types: Multitouch: No, Integrated touch: No, Integrated pen: Yes, External touch: No, External pen: Yes, Keyboard: No

Graphics Processor Info: 
DirectX: NVIDIA GeForce GTX 1070 Ti (31.0.15.1694)

What do you have for the GPU ?

So after coming back to LrC today, the AI subject selection is down to a *slightly managable* 40 seconds. Still slower than I feel it should be. Unfortunately, a little after that, Windows "updated" my GPU driver back to 30.0.101.1692, and subject select is taking three minutes again. So it does appear to be a driver issue that Intel needs to sort out, and I'm going to re-install 31.0.101.3430 and force Windows to ignore driver updates for now.

被写体の選択や空の選択などは、GPUを使用して処理をしています。

ラップトップのCPU内臓のグラフィック機能では処理が遅く、CPUで処理させた方が早いです。

環境設定からGPUの使用をOFFにして試してみてください。

GPUの使用をONとOFFでは結果が違うようです。

GPUを使用すると高精度でマスクを作成できるそうです。

画像が複雑なものに対してはGPUを使用した方が検出のクオリティが高いそうです。

 

GPUを使用して高精度で尚且つ高速に処理させたいなら、nVidiaのGeForceのようなグラフィックチップを搭載したPCの方が良いという事になります。
