I'm looking for some ideas for a major issue I'm having with flight sims - not just DCS - XP11 as well. I'm submitting to this forum because I know there's a lot of community experience here with gaming performance and problems in general and would appreciate some help.
The issue is with what I would call continual shuddering/shaking of the game images.. It happens in certain games or game configurations, but not in others. It does not happen in any other Windows 10 environment/applications, and only happens with what I assume is 3-D rendering. So not with 2-D configuration screens etc. But it also happens when the simulators are paused - not actively creating new imagery. BTW this is not stuttering where frames drop or are frozen briefly. The problem comes and goes, although lately seems more frequent. In addition to XP11 It happens with DCS World A10C, but not with DCS A10A Flaming Cliffs. Weird. This just started a week or so ago and I had not made any system changes, hardware or software prior to that. So here is the description of my troubleshooting and attempts at problem isolation. Because it was working fine for months prior to this, and nothing has changed with software or hardware, it's not a configuration performance issue.
1) CPU and GPU temps are OK and issue does not vary with length of time system is on
2) I updated the NVIDIA drivers and reset all parameters to factory (3 monitor surround is config with default resolution). Sims see one large monitor.
3) Updated Windows 10 to latest
4) Turned off Windows 10 Game Mode
5) Reset CPU and Memory to default clocks (not OC in other words)
6) Experimented with graphics parameters in games but no change in issue.
I did these in order and checked after each one to see if it helped. At one point the problem went away for a while, but then came back. Given these parameters I'm inclined to think that I don't have a software issue since it's with multiple games and I've updated the OS and drivers, and it just suddenly started happening. It's unlikely to be a CPU issue either I would think, but perhaps it is a GPU hardware problem since it seems to occur only with 3-D rendering. But I don't have any other issues like artifacts or ghosting with the GPU which would of course point more directly to the GPU. I don't have a spare graphics card to swap in/out to test this theory unfortunately.
So - I would appreciate any ideas you might have about further troubleshooting, or personal experience with this problem and its resolution.
