    Hello everyone,

    Last night, I tried load some games on cemu are: xenoblade chronicles x, Mario kart 8.... I always get very slowly on per game or crash (force close the Cemu) at starting of games.
    My computer is include: 2 x xeon e5-2670 (total are 16 cores), gpu: nvidia quadro k5000, ram 64 gb.
    I've updated the newest drivers.

    Anyone give me an advise to I can fix the problem, please!
    Thank you very much :)

    well for one thing that GPU is about half of a gtx970 which I'm running fullspeed, and you only need about 3-4 cores max, any more and you loose performance because of the added overhead.
    you want a strong single core performance which I guess you lack in those CPU's

    1. Sandy Bridge is absolete architecture.
    2. CPU's frequency is too low.
    3. Emulation is not about core numbers.

    Xeon's are really not that good at gaming, where you need really good single core performance, especially such old ones. That's not as beast a rig as you think it is, sorry.

    "Strong"...

    How has that become the default adjective for PC's & laptops now? I'm hearing it everywhere, and for some reason it just triggers me..... Everytime....

    Workstation ≠ Gaming PC

    64 GB RAM is much for a workstation.

    Not if you need to open 10+ Chrome tabs.

    Well, chrome gets less resource heavy by the update.

    Depends on the use. Often times multimedia rigs can have 128GB+ while still using a lower-end Quadro.

    That's a different game . NSMBU isn't as demanding as Xenoblade X and Mario Kart 8
    NSMBU can even run full speed on my low end laptop (i5 560M @ 3.0GHz + GT 540M)...
    As many people stated , your CPU is not good enough for Xenoblade X and Mk8 . Cemu love fast single thread performance , your CPU has many cores but each core is slow compared to latest CPU .
    Same as Dolphin emu which is a dual core application, Cemu does not support multi-core yet . That's why it run slow on your end
    An i3 6100 can easily outperform yours in single thread performance . So if you want more speed , either upgrade to the newer Haswell/Skylake or build a HTPC , solely for emulation

    Also , keep mind that your E5 2670 isn't in the same league as e5 1620
    E5 1620 run at 3.6GHz while your CPU is stuck at 2.6GHz . I'm not even sure you can play Wii Game well on this CPU , let lone WiiU

    Thank you very much, IIYAMA!
    I had always thought the problem from my GPU. I will replace my pair of CPUs or buy a Wii U console :)

    Sandy bridge architecture isn't gonna hack it for a lot of Wii-U games currently. XCX runs full speed on Skylake or better. Unless this emulator gets some really dramatic speed increases (I suppose it's possible), then Sandy Bridge probably won't ever hack it. Anyone claiming to get 25-30fps average on a Sandy Bridge on XCX is lying. And unfortunately people frequently overstate performance on specific games with specific hardware. I was misled into thinking I would get better performance than I actually got when people posted 25-30fps with the same processor, or worse than I got.

    I5 2500k even at 4.7ghz doesn't get much higher than 18fps walking around outside in XCX. With about 10fps on the low end. As of 1.7.0b. Anyone claiming otherwise is lying.
