OpenCore 7 MB VRAM Issue

I’m using OpenCore 0.5.9

My laptop specs: Intel Core i7 - 8565U Intel UHD 620

I have successfully boot into the OS, but my VRAM is showing 7 MB only and it’s laggy.

I’m using the coffee lake laptop guide, I’ve tried messing around with device-id and AAPL,ig-platform-id, the table on the guide only showing UHD 630 on coffee lake, so I tried all the possibilities, but still doesn’t work, it says Intel UHD Graphics 620 7 MB on about this mac.

Edit : I’ve also tried device-id = A53E0000, still doesn’t work
