DCS World extreme stutters with A380 and A770

[addman83]

Hello,

DCS World is one of the most popular commercial flight combat simulators on the market. I've tried to run the game with both an Acer Bifrost A770 16GB and an Asrock A380 6GB but no matter the settings, driver version or resolution, the game is a stuttery mess. Even if the fps is fine and over 100 fps etc. there is extreme amounts of stutters. I sold my A770 a year ago but kept my A380 for video editing, unfortunately I can't use it for DCS World because of the stutters. I made a video clip as an example so you can see what I mean:

I guess it's because DCS World is a DX11 title. I would hope you could take a look at it though since DCS World is such a popular title amongst the combat flightsim community.

Hi, unfortunately I sold that particular system recently. I still have the graphics card though. I was using latest version of Windows 11 Professional and the latest version of the Intel Arc Graphics drivers. Please note that I've had the same stutters on ALL drivers I've used. There was nothing wrong with my system.

Just save yourself the time and download DCS: World from: https://www.digitalcombatsimulator.com/en/downloads/world/

It's free to download and comes with a couple of free planes which you can fly. I guarantee that you will have stutters such as I demonstrated in the video on ANY Intel Arc/XE based system you try it on. Changing graphics settings doesn't change anything, you can have 100+ fps and it will still be a stuttering mess.

It's a driver issue, not a system issue.

Hello Addman83, 

Thank you so much for the suggestions.

I will raise the case with our engineers so they can try to replicate the issue, and I will get back to you as soon as I have their response.

And by the way, it is highly noted that the stutter or issue happens with all the graphics drivers.

Thank you so much for your patience.

Hello Addman83, 

Thank you so much for patiently waiting on our response.

We have replicated the stuttering issue, and our driver development team is working on a fix (no ETA for now, but it shouldn't take too long).

As a temporary workaround, we observed that disabling anti-aliasing and SSLR + SSAO greatly reduced stuttering; therefore, please perform this step in the meantime.

I will get back to you as soon as our engineers inform me about the release of the new driver that can resolve the problem.

Thank you so much again for your patience.

Best regards,

Hi @addman83,

I have good news: driver 32.0.101.6127 has been published and it introduces a fix for the issue with DCS World. Please try this driver and if the issue persists let me know.

Sorry for the very late reply but I can gladly report that this is not an issue in DCS any more. Thank you for fixing it! Further DCS performance improvements would be nice if possible, I'm seeing higher VRAM usage on my B570 10GB than on my friends RTX 5060 which has only 8GB which leads to game running out of VRAM and using shared system memory which in turn severly reduces performance in the game. Maybe Nvidia has better memory compression technology?
