Mortal Kombat 1 – PC Performance Fix Guide

Temporary fix for PC performance issues until NRS fixes it through a patch.

How to Fix Performance on PC

The Fix!

Plenty of PC users like myself having issues with the game’s performance and having to run the game at very low settings and still getting frame drops. This fixed it for me and might work for you, too.

  1. Go into your BIOS. For me this means clicking Delete during startup but for other motherboards it might be F2 or F10.
  2. Disable all e-cores. You’ll have to consult your motherboard’s manufacturer on how to do this. Shouldn’t be too hard.

That’s it. I’m running the game as I should with my AMD RX 7900 XT.

This is something nrs should fix down the line, but for now enjoy!

  1. It takes ages for me to reach character select screen but in general I think the design and programming quality needs to improve:

    1. Even though fights run properly, input recognition in training slows down – took ages to finish.
    2. Sometimes your sub-zero kameo hits / semi-freezes you instead of the opponent.
    3. Crosses’s seem to be weird compared to prior MK’s and are a mix of MK and Injustice.
    4. I admit I am running it on Ultra, but I should given my specs. But even then:
    – In hard difficulty input recognition + consistency grossly slow down unlike MK11.
    – Fights still runs fast but even if I win , input isn’t consistent for planning competitive play.
    5. Also in terms of the programming being poor. – I finished the Invasion mode allright:
    – But the final few boss fights in the final stages had way too much going on – on screen.
    – To my device’s credit, the fights didn’t hang but my game crashed before them twice.

  2. Problem for me is not fps but sometimes it takes ages to load a fighter in character select. Thats pretty annoying. Especially if you want to change some gear real quick.

  3. For nVidia users at least, new drivers came out specifically for MK1 & another game last week.

    Initially when I got MK1 over the weekend it ran poorly on all settings even with a predator helios neo with nVidia RTX 4060.

    But after the new driver I can run it in Ultra settings with very marginal jumpiness that doesn’t take away from the gameplay.

    1. Installed the new driver (there may be an equivalent new release for your graphics card).
    2. I let nVidia’s GeForce experience optimise the game – in-game auto-config isn’t the best.
    3. I shut everything else whilst running the game.
    4. You need to have the game on for at least 30min to run well.
    5. Finally – switch on upscaling in the in-game graphics setting.
    6. Upscaling disables AA mode and Chromatic aberration. You can also turn off bloom.

    With just the new drivers and without the above tweaks the benchmark claimed I was still averaging 60 fps, but without the above tweaks it did not consistently feel so.

    • But yeah the game is unnecessarily very resource intensive even for a dedicated gaming laptop, particularly in invasions fights with armor and tons of modifiers.

      You need to enable upscaling and shut off AA mode, bloom and chromatic aberration otherwise your gaming device fan really picks up in higher settings – the PC game looks better without these settings anyway.

      MK11′ s auto-config was much better and it even had frame skipping and dynamic resolution settings that helped on both low and high end devices and are missing here.

      • I’m on an AMD and didn’t do any of that. Shut off e-cores in BIOS, that’s it. All Ultra settings, never drops frames, GPU not even running hot.

      • To be honest, I didn’t have to do too much either. Mostly needed the GeForce experience to quickly install a new driver and update settings.

        I like that better than having to juggle between turning cores on and off for a game, but it’s a personal choice I respect.

        I’ve provided the rest of the information for context and as desired to ensure consistency.

        The funny thing is that before the September supposedly corrective update for the story mode, the game ran a bit better.

        But it’s good that your GPU isn’t getting hot. Mine gets a little hot sometimes, but nothing serious.
