a750 open resizable bar instead lower fps

[Timsir527]

When I don't turn on the resizable bar, the fps can reach 130~140, and the gpu usage can reach 90+, but after turning it on, the fps is left in the 70s, and the gpu usage is left 50~60.

Hello Timsir527,

Thank you for posting in Intel Communities.

Kindly be informed that enabling Smart Access Memory or Resizable BAR allows you to fully optimize the utilization of your Intel Arc A750 graphics. In your case, as you have experienced a dropped in FPS and GPU utilization when you enabled it, please provide the following information so we could investigate your issue further.

• Is it normally working before even if Smart Access Memory is enabled?
• How did you enable Smart Access Memory?
• When did you first notice this issue?
• Is this a newly integrated system?
• Any software or hardware changes made before this issue happened?
• What are the steps taken to troubleshoot the issue?
• Please provide the SSU logs so we could have a thorough look at your system. You can follow the instructions indicated on this article, How to get the Intel® System Support Utility Logs on Windows* and attach the txt file here.

Looking forward to your response. Have a nice day!

Yes, it worked normally before I turned on Smart Access Memory, and other games will get performance improvements after turning on Smart Access Memory. I turned on Smart Access Memory through bios. I discovered this problem probably in May last year. Yes, I updated the driver, and I also tried overclocking my CPU and increasing the memory from 16g to 32g, but it didn't improve the problem. Then I don't quite understand what an integrated system is.

Hello Timsir527,

Thank you for your response.

Since you mentioned that other games have improvements when you turned on the smart memory access, may we know the name of the games that has improvement and those that does not have any?

Also, you mentioned that the GPU utilization is at 50-60 could you kindly provide the screenshot showing the GPU utilization when you play games?

Looking forward to your response.

I've been busy lately, so I need to give you information later.

[Timsir527]

The game whose usage rate is not increasing is Apex, and then most games have improved. Some games will even be very laggy if the resizable bar is not enabled (CS2 and the like). This is a video I recorded.

Hello Timsir527,

No worries about it and you can take your time providing the necessary information requested.

Thanks for updating us.

With this, I just want to confirm if you have done a clean installation of your graphics driver using Display Driver Uninstaller (DDU)? If not, please follow the steps below and let us know of the outcome.

• Follow the steps indicated on the link below to do a clean installation of your graphics driver using DDU.
  • Link: https://www.intel.com/content/www/us/en/support/articles/000091878/graphics.html
• Once done, please install the latest graphics driver version 31.0.101.5186_101.5234 WHQL Certified through the link below.
  • Link: https://www.intel.com/content/www/us/en/download/785597/intel-arc-iris-xe-graphics-windows.html

My driver is already up to date, and I use DX12 mode to play apex. I wonder if it is related to the usage problem? Every time I switch back to DX11, it will be very laggy (cpu usage 100%)

[Catulpos_Intel]

Hello Timsir527,

I appreciate your response. I understand that your drivers are up to date hence, for us to ensure that it is working well on your PC, kindly try to do a clean installation of your drivers using a DDU and reinstall the latest driver. Afterwards test if the same issue happens.

Also, please indicate the previous driver versions you used on your system so we could record it accordingly.

Furthermore, switching different versions of API may also be the cause of the lagging issue however, we need the information above to further investigate and provide you with an accurate recommendation.

We hope this helps and waiting for your reply.

I have reinstalled with DDU but no improvement, the version I am using is 31.0.101.5186, I am very sad, this problem has been bothering me for a long time

Hello Timsir527,

Prior to coordinating this case with our engineers, I will be asking you a few questions so we could determine investigate the issue thoroughly.

• What version of Apex is installed on your system?
• Could you kindly provide the graphics settings used when you play this game?
• What distribution service the game was acquired from?
• Confirming that this issue happens on other graphics driver version, may we know the previous driver versions installed on your system?

We will be waiting for your response.

I installed the dx12 version of apex from steam. My graphics settings are all low (the texture streaming budget is 0g vram), and I'm sorry, I forgot what my previous driver version was.

[Catulpos_Intel]

Hello Timsir527,

Please allow us to coordinate this internally with our team for further investigation. Please be assured that we will get back to you immediately once we have a possible fix to your concern.

Thank for understanding.

Hello Timsir527,

Your issue has been checked with our engineers and for us to investigate this further, we seek additional information from you so we could replicate it on our end and find the best possible resolution.

Please provide the exact and detailed steps you took to reproduce the issue on both versions. Most especially to the game version that has the DX12 API as we have verified that DX12 is still in the beta version for Apex legends and the default API is DX11. Kindly indicate how did you enabled the game API on both versions mentioned as well.

In addition, we have tried to initially replicate the issue with our Arc A750 using DX11 and these are the results.

1. Rebar On - 190 fps

2. Rebar Off - 145 fps

As expected, the performance is higher with Rebar On than when it is turned off. As we wait for your reply, please be informed that we will require more time to investigate this matter. Hoping for your kind understanding.

Best regards,

I tried to adjust my api back to dx11 and enable rebar, but there was no improvement, and the cpu often ran to 90% and caused lag (this problem did not occur in dx12)

[Catulpos_Intel]

Hello Timsir527,

I appreciate your response; however, would you mind sharing to us the steps you took in enabling from one API to another and also the steps you took to replicate the issue you experienced so we could simulate it on our end for further investigation.

Looking forward to your response.

I entered -eac_launcher_settings SettingsDX12.json from the steam launcher

[Mike_Intel]

Hello Timsir527,

Thank you for the reply.

Can you also provide a step by step guide to replicate the issue for us to try it here in our lab?

You can share photos or videos if needed.

If you have questions, please let us know. In case we do not hear from you, we will make a follow up after 3 workings days. Thank you.
