@jumo213 Not sure you can disable the Intel part .. or what happens if you try .. it's what owns the actual buffers and circuitry which scanout to the display, and external ports. The Nvidia part renders into buffers owned by the Intel part.. it's not a separate "card" like in a desktop PC, with its own outputs (obvs). https://en.wikipedia.org/wiki/Nvidia_Optimus Let's take it from the top .. correct me if I get anything wrong. You and I both have laptops with that split Intel/Nvidia display technology. (Although my laptop is ~3 generations older.. looks like they stopped supporting it with driver updates, around 2019.) Both GPUs show up in Task Manager, but your NVidia console doesn't show the normal dropdown selection to choose which GPU to prefer .. like I showed on post #25 above. (I asked a friend with a newer gaming laptop, the dropdown is still there on her system, w/ 1050 Ti so same nvidia hardware generation. :shrug:) You get just 1-2 fps in BMS .. but other games, and benchmarks like Heaven etc run ok. My older laptop gets ~50 fps.. in BMS.. even ~18f ps with the NVidia part disabled. So we have that as a baseline target for what to expect (ie. your laptop should be much higher). So, it doesn't seem like your problem is it's just running on Intel iGPU. It seems more like it's falling back to software rasterization (WARP) but then I can't explain why your CPU usage is so low... The other red herring is your non-paged pool usage so high. Maybe that's ok? I just haven't seen anything like it before. I'm really at a loss, for where to look next. If no other ideas... if this were my machine, I would wipe the machine and reinstall windows. (Backup everything you care about, first! And maybe update the BIOS if needed.) Given the super-high npp and the weird way NVidia driver doesn't seem to understand it's on an Optimus system.. just seems like a borked install of something, to me. I give up!
