RenanPisi Nope, you can run the dxdiag whenever it's convenient. It's a system report but doesn't contain any current performance data, just some info about hardware and installed drivers and the most recent Windows error reports. Because of the WERs, it's always best to run a dxdiag soon after you see the issue (so any related errors don't get crowded out by newer ones), but that's the only possibly time-sensitive aspect of it.
snowflakecc opaozinho If you're seeing the same issue with your Mods folder removed or empty, please provide a dxdiag as well.
