Hi Biribiri7
If there are temporary changes in resolution may be because of EFB copy, go to graphics options, check, may be marked RAM, switch to texture, there are reactions of the type, instability and changes in the resolution in game play, if the problem is in the chart low resolution even with changes in the internal rate to 4x, the scaled EFB copy is disabled, select this for correction.
Please check the resolutions also.
