I'm just sticking with the 9800x3d for now as there are no extra complexities that I have to deal with. Thanks for the info.

I tried Process Lasso Pro and DCS ignores the assign core affinities and you can see DCS doing this when examining the DCS log file: system affinity mask: 11111111111111111111111111111111 process affinity mask: 11111111111111111111111111111111

I'm upgraded to the latest version and still have the same micro stuttering issues unless I change the BIOS CPPC setting from DRIVER to FREQUENCY, disabling GAME MODE in the BIOS, and change the Windows 11 power settings to PERFORMANCE. I decided to swap out the 9950x3D with a 9800x3D because I'm experiencing too many issues with other games stuttering and occasional one second frame rate pauses. I'm experiencing a 50% success rate with 9950x3d with smooth game performance and a 100% success rate with the 9800x3D. Thanks for the info, but I think the technology that the 9950x3D relies on is not stable at this time. DCS is not programmed to work with the 9950x3d at this time. I'm not having any stuttering issues with DCS with the 9800X3d, so I'll just stick with this processor for now.

I'm using the version I downloaded from the DCS web site. Thanks for clarifying that DCS is now one version. The log files shows that I am using version 2.9.14.8222, the march 19, 2025 update. I'm still having stuttering issues with DCS and the new 9950x3d system that I just built. I do not have any issues when running DCS on my older 5800x3D system with the same graphical settings. I'm currently testing DCS after changing the BIOS CPPC setting from DRIVER to FREQUENCY, disabling GAME MODE in the BIOS, and disabling Game Mode and the Game Bar in Windows 11. I'll add to this post after I do some testing this weekend.

DCS beta in its current version is NOT compatible with any of the AMD X3D and INTEL hybrid processors and states this in the first lines of the log file: 2025-04-07 06:47:41.998 WARNING EDCORE (Main): CPU HAS PARKED LOGICAL CORES (this can be source of stuttering and reduced performance especially on hybrid CPUs with P/E-cores) DCS tries to use the highest frequency cores for rendering and the other for common non-rendering processes. Here is how DCS is using my 9950x3D cores: common cores: {10, 11, 4, 5, 12, 13, 14, 15} render cores: {0, 1, 8, 9, 6, 7, 2, 3} Note that the render cores are NOT using cores 0 thru 7 with the X3D-cache as it should. The render cores are using cores 8 and 9 instead of cores 4 and 5. This will cause various levels of stuttering depending on your graphics card and graphics settings. The log shows that DCS Beta is telling Windows 11 to use ALL cores as stated in the log file: system affinity mask: 11111111111111111111111111111111 process affinity mask: 11111111111111111111111111111111 Another issue is that when the 9950x3d is correctly configured in both the BIOS and in Windows 11 for gaming, the AMD chipset drivers and the Windows 11 core schedular will constantly try to force all programs, drivers, and services to use cores 0 thru 7 which contain the X3D cache when your game has input focus. You can see this when using the MSI Afterburner overlay when playing games that are correctly using the X3D cache. Cores 0 thru 7 will be heavily utilized while cores 8 thru 15 will be in sleep mode. BUT you will occasionally see one or more of the cores 8 thru 15 wake up and immediately get put back to sleep when the new background process is switched to one of the X3D cores. The issue here is that the DCS Beta game engine is using cores 8 thru 15 that the AMD chipset drivers and Windows 11 are constantly trying to put them to sleep. NOTE that I haven't tried changing the BIOS CPPC setting from DRIVER to FREQUENCY and disabling Game Mode and the Game Bar in Windows 11, as this may be the only way to run DCS Beta with no stuttering issues when using the 9950X3D. Or as I stated earlier, another approach at this point is to enable GAME MODE in the BIOS which will disable the non-X3D cores and turn your $800 9950X3D into a $480 9800X3D with no hyperthreading.

If your are only gaming just get a 9800x3d as a 9950x3d is a waste of money. I do both productivity and gaming on the same PC which is why I bought the 9950x3d.

I get the same micro stutters when Afterburner is not running. My issue is that DCS doesn't tell the Windows 11 scheduler to park the non-cached CPUs 16 -31 when it should. I believe this has to do with how DCS is implementing multi-threading. The point of the core parking is to keep all of the game processes on the same CCD because passing game data between CCD0 (CPUs 0 - 15) and CCD1 (CPUs 16 - 31) will cause micro stutters in the program doing this. Note that I installed Lasso Pro and tried to force DCS to use CPUs cores 0 - 15, and DCS ignored the Lasso Pro settings and still used CPUs on both CCD's.

Not yet. So far the only solution is to go into the BIOS and select GAME MODE which disables the non-cached CPUS. This turns the 9950x3d into a 9800x3d. Note that when I played the game ATOMFALL, this game parked the CPU's with the vcache and used just the non-cached CPUs - weird? Note that CPUs 0 through 15 are the one's with 3d Vcache. You can use MSI Afterburner to watch which CPUs the game is using in real-time. Afterburner displays an overlay over the game.

The issue is that when gaming using the 9950x3d, you want the cores with no cache parked and the cores with the 3d cache unparked. The video show how to unpark all cores which is what DCS already does on my PC. As I stated in my post, ALL other games park the non-cache core with is the correct configuration for gaming. The only option that I have so far is to go into the BIOS and enable GAME mode which disables the non-cache cores which turns the 9950x3d into a 9800x3d.

I just built a new PC with a 9950x3d and so far all of the games but DCS use the core parking feature of the AMD chipset and the Windows 11 game scheduler. I tried using the AMD Ryzen master in game mode and DCS still does not park the non-cached cores. Another issue is that if a game doesn't use core parking, the player will experience frame stuttering in the game. Does anyone know of a solution to this problem? Like I said previously ALL of my games but DCS World park the correct cores when they are running, so this is an issue with DCS World.

That makes sense. Thanks for the info.

I was using the TGP the other day while doing a SEAD in a F-18. My technique is to place the TGP target box in the middle of the HARM box on the HUD, then I make the TGP SOI and select the target, and I also make a mark point. How does the TGP calculate the distance and location to the target if the target location is obscured by clouds? Lasers do not penetrate clouds so, this rules out laser range finding. Does the TGP use the F-18's ground radar to do this? Or, is the physics of the TGP not fully modelled in DCS when objects are obscured by clouds?

Thanks for the quick response.

I using two pylons with two each, which would be the same, correct?

OK, Thanks, so in the video by DeepHack, he had four pylons with two JDAMS each, so that is how he got four JDAMS on PP1, while I only had two pylons with two JDAMS, so I could only program two coordinates? So to program the other two, I have to which to PP2 and then duplicate what I did with PP1? When dropping the JDAMS after they are programmed, I need to select PP1 and then drop one JDAM at a time until two are dropped, an then switch to PP2 and then repeat. Is this correct?
