Intel ARC B 580 hard FPS drops in Rainbow Six Siege

[Mike6464]

I have an Intel Arc B580 Limited Edition that I just bought about 2 months ago and there are really bad FPS drops in Rainbow Six Siege.

Ram: 32GB (3000MHz)

Motherboard: Asus TUF B550 Plus

CPU: Ryzen 7 5700X (used on 4.0 GHz)

GPU: Intel Arc B580 Limited Edition (driver: 32.0.101.6739, 2025.04.23)

Windows 10 Pro 64-bit 22H2

When I play Rainbow Six Siege I have the FPS locked to 120 and it frequently drops to 2 FPS then goes back up to 120. I tried to change the game settings but it didn't make any difference. And I noticed that this usually happens when I have something opened that uses the video card and it makes the game(or the video card) unstable. For example if I open opera or discord and it uses hardware acceleration then it becomes unstable and sometimes crashes. Now if I close everything that uses the video card except for the game, it sometimes solves the problem. Although I had a previous video card in my build before but I used DDU and reinstalled the whole system already. I tried reinstalling the game, it didn't help. I used SSU, the generated file will be below.

Can someone help me with this ?

Hi Mike6464,

Thank you for reaching out to the Intel Community Forum. To assist us in investigating the issue, please provide the following details:

• Does the issue occur only during cutscenes? Or does it also happen during regular gameplay or menus?
• Could you provide a screenshot of your in-game display and graphics settings?
• Which gaming platform did you use to download the game?
• When the FPS drops occur, do you observe any unusual activity in the Task Manager, such as high CPU or GPU usage?
• Have you tried disabling hardware acceleration in applications like Opera and Discord to see if it affects the stability of the game?

If you have any questions, please let us know. Thank you.

Best regards,

Hi.

1. This issue occures when I'm in the game. It doesn't matter if I'm in the lobby or in a match. Even during cutscenes. But when I'm in a round playing/spectating it lags more frequently.

2. I'll provide some screenshots below.

3. I bought the game from ubisoft and play it through the ubisoft connect launcher.

4. When the drops happen the GPU usage of the game goes up but the CPU doesn't. Mostly the GPU goes to a 100%.

5. Yes I tried and sometimes it worked. However, not always and in opera the hardware acceleration is not turned on and if it's open the game starts getting the lags. But sometimes after a PC restart I only open the game and it still lags. So it's probably not just that. If I play while opera is closed and have discord open without hardware acceleration sometimes it doesn't lag but sometimes it does.

I tried a few changes in the display settings of the game but it didn't solve it.

Hi Mike6464,

Thank you for the update. To resolve this, please follow this:

Use Vulkan as the rendering API for this game. To enable this:

• Select Rainbow Six: Siege in your Ubisoft Connect library. (This step is applicable even if you have purchased the game on a different game launcher).
• Click Play.
• When prompted Select Tom Clancy's Rainbow Six Siege - Vulkan from the drop-down menu (or the menu your launcher shows).

Check the Always use this option. If you don't, you will always have to choose the option for launching on Vulkan.

If you have any questions, please let us know. Thank you.

Hi.

As far as I know Ubisoft has removed the Vulkan API from the game. Right now there is no popup when starting the game and nothing in the settings of ubisoft for the game.

Hi Mike6464,

Thank you for the update. Since this is the case, I would like to request for a CapFrameX log for further analysis. Please make sure to play the game for at least 2 minutes to properly evaluate its performance. For guidance, please visit Need help? Reporting a bug or issue with Arc GPU? - PLEASE READ THIS FIRST!. If you need assistance, we can arrange a remote session to help you obtain this log. If you have any questions, please feel free to reach out. Thank you.

Hi.

Unfortunatly I couldn't download the overlay for CapFrameX. The web page said "(Virus scan in progress ...)" and I just couldn't download it. However I checked some overlay boxes that I thought was important and made the JSON file which I will provide below.

Hi Mike6464,

Thank you for providing the CapFrameX. I will now further investigate this and will get back to you once a resolution is available. Thank you for your patience and understanding.

Hi Mike6464,

I kindly request that you update your graphics driver to 32.101.6790 WHQL Certified (Latest). After completing the update, please test to determine if the issue still occurs.

If the problem continues, I would like to request for an updated SSU and CapFrameX so I can further look into this. 

If you have any questions, please let us know. Thank you.

Hi.

With the new driver it's certainly better but it's still bad. I will provide the files below.

Hi @Mike6464,

I am reaching out to you on behalf of our technician, ArchieD_Intel, regarding the issue you have encountered. I am currently investigating the matter and will provide you with an update as soon as possible.

Your patience and understanding are greatly appreciated. If you have any immediate questions or concerns, please feel free to contact me directly.

Hi.

I'd like to inform you that I have found a solution. In the Intel Graphics Software under the Graphics option if I turn the Low Latency mode off, the lags go away. I used "On + turbo" and I haven't tested the "on" option itself but turning it off works for me.

[ArchieD_Intel]

Hi Mike6464,

Thank you for the update. I appreciate your efforts in helping us understand the issue better. I have attempted to recreate the problem you encountered with your graphics card using the settings you provided, specifically with the latest Intel Arc Graphics version: 32.0.101.6793. During our tests, I did not experience the same frame drops you mentioned.

Our tests included various settings:

• Low latency: Off with Intel Arc B580 using version 32.0.101.6793
• Low latency: On with Intel Arc B580 using version 32.0.101.6793
• Low latency: On + Boost with Intel Arc B580 using version 32.0.101.6793
• Low latency: NVIDIA RTX 4060 with version 32.0.15.7640

In comparison with the performance of a third-party competitor, the Intel Arc B580 graphics card is performing within its expected level when playing the game.

I encourage you to test the latest graphics driver and share your feedback on our findings. If the issue persists, please be aware that it may not be driver-related but could be related to your system configuration. Rest assured, Intel will continue to assist you in isolating and addressing the issue. To help us further, please provide an updated SSU of your system and the latest CapframeX data.

Thank you for your cooperation and patience.
