Scroll up to the GPU thread, the screenshot is meaningless without knowing what the Rendering thread is doing. You should also attach a Microprofiler dump with one of these spikes for further investigation by the engineers.
IntelliSense can’t be causing rendering spikes because it has nothing to do with rendering.
i was just saying this happened during the intellisense and explorer update, also has this not occurred in your game it seems its only for the developers though and sorry but i have no idea on how to use the micro profiler does if im being honest i just screenshotted what showed up in the lag spike
