    Win some Lose some.

    Well this is not a complaint about Steves DX10 but a lesson learned about low end systems and FSX. After much consideration I obtained the DX10 Fixer and installed it on my system.

    Here is the outcome, it did everything it claimed, so 10/10 for that. The changes were great, particular the shadows which the Fixer even had showing in older Legacy aircraft quite well and I really love the cloud shadows on the ground and water. Overall it was wonderful and I was very satisfied BUT and here is the BUT, it killed my sim performance to the point of being almost unusable with DX10 selected. My FPS dropped from locked 30 to 6 and sometime even 2. There was no tearing or graphic flashes, just slow slow slow.

    I investigated a number of tweaks I had no considered before but they only marginally improved the loss of performance as measured by FPS, curiously it was worse from the VC but improved with the outside view.

    So near yet so far. The issue - while I had a 4.0GHZ CPU with 8 GB DDR RAM and a 2GB Video card, it was an older dual core Intel system and because it was an off the shelf system it had an older Intel G41 Video card and it was quite clear that FSX was overwhelming the GPU for the video card, end of story. So whilst DX10 did everything it said it would and the results were tantalising good not on this older system. So DX10 was deselected and I am back to DX9.

    Solution well first as I always thought would be the case there is only such much performance you can squeeze out of the older hardware and chips and I can thank the DX10 Fixer for really making this very clear. So the only solution if I want those goodies, a new PC with a high performance CPU and a high performance Video GPU.

    Hi, I would strongly recommend posting on Steve's forum. He is very helpful and may be able to steer you to a solution.

    Have you created an Nvidia Inspector profile for Dx10?
    SYSTEM :
    OS:Win7 Home Premium 64 bit UAC OFF!
    DX version Dx10 with Steve's Fixer.
    Processor:I5 4670k overclocked to 4.4 gHz with Corsair CW-9060008-WW hydro cooler
    RAM:16 gig 1866 gigaHz Corsair ram
    Video Card:MSI 1070 8 gig ram
    HD:2Tb Samsung 850 evo SSD

    To err is human; to forgive is divine

    Another thing which may assist, are you running full screen? Try winowed mode BUT utilise the freeware program available at Avsim. That increased my fps significantly.
    Intel i5-8600K 3.6 GHz Coffee Lake 6 Core Processor
    Asus ROG Strix Z370-E Gaming LGA1151 Z370 Motherboard
    Corsair Vengeance LPX 32GB (4 x 8GB) DDR4-3200 Memory
    Corsair 100i Liquid CPU Cooler
    Corsair 1000W PSU
    MSI RX580 Radeon Armor 8Gb
    Windows 10 Home Premium 64

    Thanks for both suggestions will do for both. By the way this is not a complaint about DX10 but it perversely demonstrates the limits of systems that were about when FSX came out, with what it can do. Part of my problem is both the dual core limit and the Video Card GPU. The Intel video card is actually very good and matches my system well but neither can work fast enough when DX10 is brought into play to refresh the graphics as they are being collected and sent to the video card. Will look at the monitor issues as well.
