Hi deak2 big,
Even with specs like ours we should be able to manage a reasonable frame-rate in all cases. Within Fs there is a lot of difference between the aircraft’s in general. The A-320 is not yet optimized, so if you add this to the sim itself, which also needs optimization, you won’t get the performance that matches your specs.
In your case I’m almost sure there are settings that can be aligned to gain reasonable frame-rates even when flying big airports. In my case I’m trying to figure out if any upgrade would solve performance problems. As you know some of us bought expensive hardware and still are struggling with performance problems.
I’m not counting on 100fps in the future even when the sim is balanced but aiming for 60fps. DX-12 will enhance Fs but won’t “fix” all problems.
In your case I would try to figure out what causes your bottleneck at this time. Even when my specs are lower then yours I run 35+ as an average without turning off normal settings. Tuning Fs is a strategy which is very Pc depended so following different good intended tricks can result in worse performance.
