After replacing the motherboard, there was an issue with Battlefield 2042.

It turns out my motherboard was the MSI B450M Mortar MAX. When playing Battlefield 2042, even though CPU usage would reach 100%, there were no stuttering issues.

But after switching to the ASUS B550M TUF GAMING PLUS WIFI II motherboard, I experienced severe stuttering and couldn't play the game properly.

Apart from the motherboard, no other hardware has been changed.

CPU:AMD 5700x

memory:16G*2 2133/2400/3200/XMP3600/OC3800MHz

Graphics card :ASUS RX9070GRE

psu:COUGAR GX1050w

Changes already attempted:

  1. Changed Windows version to 10 or 11.
  2. Updated the BIOS to the latest version and then downgraded to the version released in October 2023.
  3. Replaced with memory from another brand, 8GB * 2, 2400 MHz.
  4. Disabled any overclocking options, power-saving options, TPM, and trusted computing in the BIOS.
  5. Used user.cfg to limit cores and threads.
  6. Changed the PCIe 16x_1 interface protocol for the graphics card to Gen3 (this had the biggest improvement, but it only works for infantry on the ground; high-speed movements like TV or jets still cause stuttering).
  7. Moved the graphics card to the second slot, running in PCI_E 3.0 *4 mode.
  8. Tested using FurMark and AIDA64, both GPU and CPU were at 100%, but no fluctuation like in the image occurred.
  9. The temperatures of the CPU and GPU are normal. The CPU doesn't exceed 80°C, and the GPU doesn't exceed 60°C.

After trying these things with no effect, I thought the power supply or CPU might be the problem. Since I didn’t change any other components, I switched back to the B450M motherboard, and everything returned to normal. Then, I had the retailer replace it with another B550 motherboard, but the stuttering issue remained.

The stuttering is accompanied by CPU and GPU utilization fluctuating in a sawtooth pattern. During detection, the CPU power drops. For example, during gameplay, it's at 110W, but during stuttering, the power drops to 60W, as shown in the image below.

    I’ve checked, and there isn’t a separate VRM temperature option. These usually appear on newer motherboard models, such as the B650 or B850.

     

    Then today I replaced the PSU, but the issue still persists, so it’s not a power supply problem. I’m now trying to move Windows and the game back to the original SSD. A friend said that the new drive might not be suitable for running the system — it’s only good as a game storage drive.

    A drive's a drive. Generally that shouldnt have any bearing on things. All signs are pointing to SOMETHING with the motherboard its just the exact bit thats eluding everyone here.

    I think there's something wrong with the motherboard design, so I'll have to go through the trouble of switching back to a B450 motherboard. No more trouble, just let the B450m accompany me to the end.

     

    I give up.

    The first thing I check with a new motherboard is to make sure all the screws for the VRM heat sink are tight. The last motherboard I bought came with loose VRM heat sink screws right out of the box.

    The second thing I check with a new motherboard is visually inspect all the copper pins in the RAM slots and CPU socket to make sure none of the pins are bent. That's another common manufacturing defect on motherboards.

    I believe the VRM of the B550M motherboard is not the issue because it passed the CPU FPU stress test, Ryzen Master overclocking test, and can run World of Warcraft, Overwatch, and Black Myth: Wukong without problems. I switched back to my old motherboard without reinstalling the system or modifying any settings, and everything returned to normal. Now I can play Battlefield 2042 without issues. I think the root of the problem might lie in the driver optimization for the RX 9070 series graphics card, and it may take a long time for AMD to release a fix. In the end, this issue remains unanswered. That’s it. Thanks to everyone for following this post, and I wish you all a wonderful day. Thank you.
