What are your default rendering settings, lets start there Mad..... What kind of scenery, what location, are you using HD mesh...... What aircraft are you flying also this has something to do with performance.... A list of plugins running would be nice.... Do you have an optomized OS? Cut of unwanted processes, programs to help performance.... Drivers Up to date?...... Have you cleaned up your plugins folder?......... I need information to help you out Mad, but as you said in a previous post you are not happy with the product. If that is the case and you do not wish for a solution you are trolling these forums. If you would like to continue this conversation and work through your problems we have a group here that will be more than happy to help you.
