I'm currently running on Windows 10 Home Edition 64bits, My PC is running thanks to an beatiful Intel Core i7 5820k @ 4.2ghz and 16GB DDR4 2666MHZ, and I run the OS on a Samsung 850 EVO 250GB SSD and the Flight Simulator X Steam Edition on a 500GB Samsung 850 EVO SSD, My video card is a EVGA Nvidia Geforce GTX 980 Ti 384 bits 6GB GDDR5 ACX 2.0 SC, my all drivers are up to date!
Here is the main problem I have listed from just putting 1 tweak to like every know tweak in the fsx community and I get low frames I can even get pass 10 - 28fps using the A2A Cessna 172 at Mallorca X Evolution and just 40fps with the Ultralight at Friday Harbor. Ok Yes I run with 4096 REX 4/Soft Clouds textures but supposely my pc is capable for that and more and other people run it with worse specs and better specs with the same sliders and Texture max load! I had downloaded others people cfg, make a clean cfg, tweaked with ******* Venetubo tool, tweaked manually, just put Affinity mask, bufferpools alone etc.. then together and like that and still no perfomance! Same fps on DX9 and DX10, and no gain on fps. For those thinking ins't the PC as I run normally any stress test, 3DS MAX 2016, Battlefield 4, SMITE, LoL, Unreal Engine 4, even Witcher 3 and Phantom Pain ultra 60fps @ 1080p! and with flight sim I just can't stop experiencing low fps, lag spikes, stutteres, slow loading texture, OOM, CTD when Switching full screen to windowed and vice versa. I'm really deseperate as I had been saving a lot for this PC to use it for Flight Sim purpose to give me this result and I know is capable running at least 40fps with almost everything maxed on the most demading scenarios, aircraft and settings without any problem. Is the 3rd time I reinstall FSX: SE (Clean unistallation and reinstalls!) which is a pain reinstalling the add-ons again!
I just hope the community can help me fixing this issue, thanks you!
