Hi, I just got a brand new Lenovo laptop with the new 10th gen intel i7-1065G7 cpu.
Problem is it’s very sluggish with Blender 2.80 and 2.81 with just a box in the viewport(about 10 fps).
Runs smooth in 2.79, Houdini and other 3D apps.
I wonder if it’s something to do with the new iris plus integrated graphics.
Hope something can be done.
out of curiosity, on which system?
have you tried the latest drivers?
try starting blender with blender --debug-gpu-force-workarounds
and see if the situation improves,
I know that workarounds have been created for Intel GPUs, but maybe your model is not included and may need it …
It’s the new lenovo yoga c940 with windows 10.
I’ve updated everything through lenovo but I’ve found a newer graphics driver on intels page. It won’t let me install it because it’s not a validated lenovo driver. This might be the issue although everything except Blender 2.8 runs great.
I’ve tried blender --debug-gpu-force-workarounds and it makes no difference.
I don’t have a solution …
just a question … where did you get these 10 frames per second?
perhaps they do not correspond to a real reading …
do one thing … download some demos from here and make and post a video by activating eevee realtime rendering … from there I can tell you if in my opinion you have real problems or not.
The 10 frames was an estimate when navigating in the viewport with just a cube. Scrubbing the timeline with just the cube is also extremely slow. I’ve worked professionally with 3D for 15 years I know when performance is completely off and this is just a grey cube in solid mode.
I have the same problem (laggy interface, even moving the window is laggy!)
Did you find a workarround or any hints?
Intel® Core™ i7-1065G7 CPU, Windows 10 Pro.
By the way, blender 2.79 is running fine on the same machine!
