Generation speed slower than A1111

Open Kenqr opened this issue 11 months ago • 1 comments

GPU: RX6650XT Command args: --use-zluda (--use-zluda --medvram --medvram-sdxl in A1111) Generation time for a 768x864 image using a Pony based model: 70 seconds (46 seconds in A1111)

After fresh install, forge was taking 121 seconds to generate an image with the same model and same dimensions. After changing the optimization settings to match my A1111 settings, it's takes 70 seconds now, but still longer than 46 seconds in A1111.

Is there anything else I need to configure to make forge run faster?

Hey you can remove --medvram as --medvram-sdxl enables medvram only for sdxl, where its needed for GPUs with 8gb vram. That should speed up 1.5 based models. You can try add --cuda-stream for speed improvements. Also if you have only 16gb of RAM you should increase the Windows Pagefile. That will speed up the gen time for SDXL models. Also make sure Wallpaper Engine, Games or a lot of Browser Tabs are not running in the Background. These will slow down too.
