I'm recently experiencing some quite annoying framerate drops/stuttering in the game War Thunder, mostly in its Air Realistic Battle mode.
I'm playing the game in 3840x2160 resolution at Max preset quality, with V-Sync On, and the game runs at stable 60 fps (while the GPU can push to stable >100 fps in this quality setting with V-Sync Off).
For the last half month, I started experiencing some framerate drops down to 30-50 fps frequently when I'm playing the game, and this seemed to be related to the rendering of engine exhaust (it occurred every time I viewed close to the WEP throttle engine exhaust). With the most recent driver update, this framerate drop has changed to quick stutters, which is even worse than the former, making some parts of the game borderline unplayable. This is happening almost every match.
Attached are screen recordings of the several instances where the stuttering occured. In-game framerate is displayed on the bottom-left corner.
Is this a driver-related issue? If so, can this problem be addressed?

Hi, Dr_Who_4.
It’s interesting that rolling back to the previous driver resolved the stuttering but caused occasional framerate drops, and that reinstalling the latest driver has improved things for now. This could point to a more complex interaction between your system setup and the drivers.
Please try the troubleshooting steps below:
- Confirm there are no BIOS or Operating System updates missing.
- Check with the motherboard manufacturer for BIOS updates and instructions on how to apply them.
- Update the Intel® Processor Graphics driver.
- Follow How to Install an Intel® Graphics Driver in Windows® 10 and Windows 11.
- If a dedicated graphics card is in use, download the latest driver from the graphics card manufacturer and update it according to their instructions. Visit Download Center to get the latest drivers for Intel® Arc Graphics GPUs.
- Check the power plan settings.
- Press Windows + R.
- In the Run window, type powercfg.cpl and press OK.
- Under Choose or customize a power plan, the currently selected power plan is displayed (set to Balanced by default). To the right of the current power plan, select the option for Change plan settings.
- Click Change advanced power settings.
- Scroll down, find Processor power management and expand it.
- Expand Maximum processor state.
- Double-click On battery and set the value to 100, then do the same for Plugged in.
- Click Apply, then click OK to exit.
- Turn off the Windows Game Bar and Game DVR.
- Press Windows + S.
- In the Windows search box type Game bar settings and press Enter.
- Under Control how Game Bar opens and recognizes your game turn off the option for Record game clips, screenshots and broadcast using Game bar.
- From the left had menu, directly below Game Bar, select Game DVR.
- Turn off the Record in the background while I’m playing a game setting.
- If applicable, test the configuration without the dedicated video card, (i.e. using just Integrated Graphics) or test the configuration using another dedicated video card (if possible).
- If the same issue can be observed, contact the game developer.
Best regards,

Hi, Dr_Who_4.
Thank you for posting in our Community. I understand that you're experiencing significant performance issues in War Thunder, particularly related to the rendering of engine exhaust in Air Realistic Battle mode. Based on the details you provided, this could indeed be related to the driver update, as you've noticed changes after it. If you've already tried any solutions to fix this issue, please let me know what you've done so far to avoid repeating any steps.
Let's dig deeper by checking the graphics models, exact driver versions, and any system errors. Using the Intel SSU tool will help us gather detailed information about your system setup, which could pinpoint the root cause of this issue. Additionally, please provide CapFrameX data for this game. This will help us analyze performance metrics more thoroughly and identify any issues. However, please share a CapFrameX file that captures at least 5 minutes of gameplay.
Have a nice day!
Best regards,
Von M.

Hi Von,
It did feels like a driver-related issue, but now I'm not very sure what's the root cause of the problem.
Yesterday after posting I rolled back my driver to version 32.0.101.6449_101.6256 WHQL Certified, and the stuttering issue consisted. So I rebooted my system, relaunched the game, and the stutters were gone. Though with this older driver, the framerate drop issues occasionally reappeared.
Now I have reinstalled the latest driver (32.0.101.6557_101.6262), and it seems that for now the game is running relatively smoothly. This is very strange to me lol. If I encounter a similar issue in the following few days, I'll follow up under this post.
Below is my system info gathered by SSU and several >5 minute long CapFrameX captures after I reinstalled the latest driver today.
PS: I took me a while to find my CapFrameX configuration folder, which isn't under %userprofile%\Documents\CapFrameX\Configuration; instead, I found it by clicking "Open configuration folder" in the Overlay tab of CapFrameX, in which case the folder is under my %userprofile%\AppData\Roaming\CapFrameX\Configuration. Dunno if this is a valuable note for a ReadMe update?

Hi Von,
I think the problem's likely solved with turning the Game Bar off. I'm not experiencing stutters for quite a while now, though occasionally it still happens for a fraction of second (the magnitude doesn't matter at all now). I also feel that these kind of issues are quite tiring to nail down, from both my side and your side, so I think now it is a good time to call this case closed.
Thank you so much for your advice!
Andy.

Hello, Dr_Who_4.
I’m really glad to hear that turning off the Game Bar has helped reduce the stutters. I completely understand how these kinds of issues can be exhausting to troubleshoot, so I’m happy we’ve made progress. I appreciate your thorough troubleshooting. This will be helpful for others who might encounter a similar issue in the future. I appreciate your patience and cooperation throughout this process. If anything comes up again, don’t hesitate to reach out.
I will close this inquiry now. If you need further assistance, please submit a new question as this thread will no longer be monitored.
