Hello, I was playing War Thunder and I recorded a great video of my gameplay. When the match ended, I went to check the video. I opened it and found that it was corrupted and incomplete. (Note: this kind of video corruption happened to me on 4 different graphics cards, so it seems like a general issue.)

When I tried to skip to the end of the video, the screen suddenly went completely black and the system froze for about 5 seconds, then everything returned to normal. I checked the Event Viewer and found 160 nvlddmkm errors

I initially thought the GPU had stopped working due to a VRAM issue, so I ran an OCCT test for an hour and a half with 96% VRAM usage and found no errors.

I checked the video again and the same scenario happened: the PC froze, then I got a blue screen not bsod just the wallpaper changed to blue screen for about 5 seconds, and everything returned to normal afterward. I also saw two nvlddmkm errors.

My NVIDIA Instant Replay recordings are stored on an HDD, and the temporary files are also on the HDD.

Someone advised me to move the video to an SSD, so I did. I opened the video again and skipped near the end, and I got a black screen without a full freeze, along with about 20 nvlddmkm errors.

I tested 100 other videos and nothing happened.

So what is your explanation for this?

Could I have created a video that causes the system and driver to crash?

First of all, my specs are:

RTX 5070 Ti

i5-14600K

16GB DDR4 3200MHz

B760 ProArt DDR4 motherboard

TeamGroup Gen 3 M.2 512GB

1TB HDD

I’m experiencing micro stuttering in most games and I can’t figure out what is causing it. I recently ran HWInfo64 while the stuttering was happening, but I still can’t identify the issue.

Previously, I also had another RTX 5070 Ti, but it died because of a VRAM problem. The same stuttering issue I have now was also present on the old card.

Now I have a completely new RTX 5070 Ti and I still have stuttering.

I tested my M.2 SSD and these are the read/write speeds.

Should I buy a new M.2 SSD, or is the issue caused by another component?

Note: I experience stuttering in War Thunder that happens twice every 3 match and then disappears. The strange thing is that disabling V-Sync from the NVIDIA settings fixes the issue in War Thunder.

However, in other games, disabling V-Sync does not fix the problem.

I would appreciate any help or suggestions.

Thank you.

I’ve always wished to play this game in 4K on ultra settings. And now my dream has come true.

But I have a question: is anyone experiencing micro stuttering when entering a new area or when new enemies appear?

There’s no stuttering when I’m fighting bosses or just exploring the area.

I found someone who has the same problem. https://learn.microsoft.com/en-us/answers/questions/3874819/background-flickers-briefly-after-toggling-task-vi?forum=windows-all&page=2
