DeNoise on MS Surface 3

I have installed onto my rather older Microsoft Surface 3 and AI DeNoise is basically useless. It took close to five minutes just to do a test image. I have read some other threads here, but it seems I may be SOL? I was hoping to edit while on a trip next month but it’s looking like Topaz might have to wait until I am back and on a desktop with tons of GPU? The GPU was maxed at at 100% the entire time Topaz was trying to apply the settings? Are there any secrets that might improve performance on the Surface3?

My Surface 4 works ok with Topaz, as long as I close PS and LR and Chrome beforehand, and work only in Standalone.
