You read it right. My gaming laptop (Razer) has both intel an nvidia gpus. Overwatch says its using the Nvidia GPU on the options screen, but it clearly isn’t. The GPU is at 0% in task manager and the intel GPU is at almost 100%. The frame rate is 30 FPS on low.
Standard question: are your GPU drivers up to date?
This is happening to me as well, but the weird thing is, its only in overwatch. If i play any other game the task manager GPU shows usage, but with OW its like 1 %. Iv got my intergrated gfx disabled so i know its still using it
