Now you are ready to start tweaking and testing your FSX. Then you may proceed with obligatory HIGHMEMFIX. Then navigate to your fsx.cfg location and make a backup copy. Add UIAutomationCore.dll to your FSX folder. Tweaking – the general idea and procedureĪs I already wrote – make sure that you have SP2 or Acceleration or FSX:SE installed. I omitted elements that should not be edited and some that are not relevant to performance and graphics. Your fsx.cfg may include more lines that I described here. ĭouble slash – // – marks comment – a part of line (or the whole line) that will be ignored by FSX. Section headers are wrapped in square brackets. It is a simple configuration file that uses single line commands containing a name of the setting and value with “=” character in between. In my opinion it’s best not to use FSX display menu at all. Be aware that changes in FSX settins may overwrite your fsx.cfg tweaks.

I will indicate in this guide which values change positions of sliders in FSX settings. There are some outdated tweaks – leftovers from earlier version of FSX (SP1 or base version without any Service Packs) or even earlier version of Flight Simulator. Some may improve your performance or quality. FSX:SE (Steam Edition – service packs and Acceleration included – do not install)Īll other fsx.cfg modifications and tweaks are not obligatory.FSX with Acceleration pack (service packs included – do not install).FSX with SP1 and SP2 (installed in this order).Not a tweak per se but I feel it is important to mention that you need to have a proper FSX version installed. Fix required for correct memory addressing during texture loading (helps prevent OOM errors). Not necessary in FSX Steam Edition. Highmemfix=1 – place under headline in your FSX.cfg file.
