X-Plane's .......post a screenshot of the rendering window.... A couple areas of interest are water reflections and draw distance.... Many people put water reflections to high, honestly the difference between high and low isn't even noticeable...but setting it to high is very expensive on resources..... Also draw distance can also be knocked down to either....medium or high......very high takes a huge toll on the sim...... This should help to negate any hardware/ software mismatches..... In the SMP dialog keep cloud quality to 1/3 Overcast quality to medium And cloud draw distance to 3/4 Just a few things to get you started, but if you tackle a few settings you will not miss much in X-Plane and gain better performance.... Both SMP and X-Plane are scalable, even for future hardware.......
