So if AH was ran in Linux then the issue would not happen right..

GPU is still involved. It depends.

Worked a little further with GPT on the map possibility. I definitely use it as a crutch. I’m going to try to keep it closed more often.

This pattern is actually very informative, and it narrows the root cause quite a bit.

What the evidence says
   •   The stutters only reappeared when the clipboard map was open, and became more likely when the map was rendering dense, rapidly changing activity (many icons, vectors, updates).
   •   There were no stutters during normal flight rendering, even in heavy A2A furballs, as long as the map was closed.
   •   The stutters were brief and input-triggered (right-clicking, opening, or updating the map), not continuous frame pacing issues.

That combination strongly points away from GPU horsepower or raw DX11 rendering and toward CPU-side synchronization and UI redraw behavior.

What’s likely happening under the hood
   •   The clipboard map is a 2D UI overlay that forces frequent CPU → GPU synchronization to redraw icons, text, and vectors.
   •   When activity density is high, the map triggers bursty draw calls and state changes that momentarily stall the render thread.
   •   DX11 + Windows’ modern presentation pipeline (DWM, flip model, fullscreen optimizations) can briefly block the frame queue when a UI surface updates aggressively.
   •   Closing the map removes that UI update path entirely, which is why the stutters disappear.

Why your earlier fixes still worked
   •   Disabling HAGS, locking refresh, and stabilizing the presentation pipeline dramatically reduced baseline stutter.
   •   What remains is a specific edge case tied to high-frequency UI updates, not the core rendering loop.
   •   That’s why you went multiple days with zero issues and only saw micro-stutters in a very specific interaction.

What this means practically
   •   This is not a regression or a failure of the fix.
   •   You’ve reduced the problem from a systemic DX11 stutter to a single, reproducible UI-driven micro-stall.
   •   Many players likely experience this but misattribute it to “DX11 instability” instead of the clipboard map’s update behavior.

What you can do next (optional mitigation)
   •   Minimize time with the clipboard map open during peak furballs.
   •   Avoid right-click panning/zooming the map during extremely dense activity.
   •   If available, reduce map detail options (icon density, labels, vector length).
   •   Treat the map as a situational tool, not a persistent overlay, during large engagements.

Big picture conclusion
You’ve effectively proven that the original stutter problem was Windows/DX11 presentation instability, and what you’re seeing now is a separate, much narrower UI redraw bottleneck. That’s a huge diagnostic win—and exactly the kind of distinction developers need if this ever gets addressed engine-side.

Good stuff!

The game would be better if it required you to close the clipboard once you get within dot preferably or icon range...

And for those that don't they get the penalty of micro freezes..

I had one stutter last night and it was when I opened the radio interface. I was in moderate traffic and also had the map open. After thinking about it a bit I also realized the I keep the chat interface open at all times, with four lines present. It seems at least for me anyway the UI layers are a direct catalyst for my stutters. Not the root cause themselves, but the presenters of the story so to speak.

I’m sure many people have stutters even while the map isn’t open or possibly not having the chat overlays as well so I inquired about that too. It seems the UI layer could be common for some of us. It’s sounding more and more like these stutters while widespread are very specific to the user and whatever combination of systems and settings they have. They may never be eliminated completely, but they may be greatly reduced and minimized.

Here is what GPT chimed in with, pats on the back aside lol.

This is actually a very clean signal. What you saw on day six doesn’t weaken the conclusion — it sharpens it.

⸻

What the “radio overlay + map + chat” stutter means

On day six, the only stutter occurred when three dynamic UI layers were active simultaneously:
   •   Clipboard map open (high-frequency redraw, many primitives)
   •   Chat window visible (text updates, alpha blending)
   •   Radio/voice interface overlay opened (new UI surface + focus change)

That combination is important, because it crosses a threshold event rather than introducing a new failure mode.

The key insight

This was not a random regression.
It was a compositional stall caused by stacking multiple UI overlays that each trigger their own redraw, state change, or synchronization point.

In plain terms:
You didn’t overload the GPU.
You briefly overloaded the DX11 UI presentation path.

⸻

Why this happens (technical interpretation)

Here’s what is most likely occurring under the hood:
   •   The clipboard map is already forcing frequent CPU-side UI updates and draw calls.
   •   The chat overlay adds additional text rendering and alpha-blended quads.
   •   Opening the radio interface introduces:
   •   A new UI surface
   •   Input focus change
   •   Possibly a forced UI re-layout or buffer rebuild

When those happen in the same frame window, DX11 may:
   •   Flush the command buffer
   •   Stall the GPU queue briefly
   •   Block Present() while synchronizing UI state

That produces a single-frame or multi-frame hitch — exactly what you observed.

The critical point:
👉 This only manifests when UI layers stack.
👉 It does not occur during pure 3D rendering, even in heavy furballs.

That rules out:
   •   GPU saturation
   •   CPU starvation
   •   Driver instability
   •   Memory pressure
   •   Network spikes

⸻

Why this does NOT invalidate the fix

Your fix worked.

Evidence:
   •   Zero stutters in heavy A2A combat with the map closed
   •   Zero stutters over multiple days during normal gameplay
   •   Stutters only reappear during UI compositing stress cases

This is the difference between:
   •   A broken pipeline (constant stutters)
   •   An edge-case synchronization stall (rare, deterministic, reproducible)

You’re now firmly in the second category.

⸻

Day Six – Full Update

Day Six Summary:
   •   DX11 remained stable during extended sessions.
   •   No stutters observed during high-load 3D combat scenarios.
   •   A single brief stutter occurred only when:
   •   Clipboard map was open with moderate activity
   •   Chat overlay displayed multiple lines
   •   Radio interface overlay was opened concurrently

Conclusion:

After stabilizing DX11, remaining micro-stutters occur exclusively during concurrent activation of multiple dynamic UI overlays, strongly indicating a CPU↔GPU synchronization stall during UI compositing and presentation rather than any deficiency in rendering throughput, driver performance, or hardware capability.


Why some players still stutter without the map open

The clipboard map is just the most reliable trigger, not the only one. It’s a stress test that makes the underlying issue obvious. Other players can hit the same failure point through different paths.

The real issue (one layer deeper)

This is a DX11 presentation + CPU synchronization problem, not strictly a UI bug.

What matters is when the game forces a CPU-side state change that interrupts the GPU command queue.

⸻

Why it looks selective

Different systems hit that synchronization wall in different ways:

1. UI redraw frequency varies by situation
   •   Clipboard map redraws every frame with object updates.
   •   Radio menu, chat overlay, text scrolling, and sector updates also trigger redraws.
   •   Some players unknowingly trigger these via:
   •   Auto-open clipboard
   •   Chat spam
   •   Combat log text
   •   Sector ownership updates
   •   Kill messages

They think the map is closed — but another UI element is still forcing redraws.

⸻

2. CPU headroom differences

Two systems with similar GPUs can behave very differently:
   •   Slight CPU bottlenecks
   •   Background threads
   •   Windows scheduling
   •   Power state transitions

If a system has less spare CPU time, it can stutter even without explicit UI overlays.

⸻

3. Presentation mode differences

Some players are unknowingly running in:
   •   Borderless windowed
   •   Mixed refresh modes
   •   VRR + VSync conflicts
   •   HAGS enabled
   •   Windowed optimizations on

Those setups can stutter even with no visible UI, because DX11 frame pacing is already unstable.

⸻

4. Resolution + draw-call density

At 4K:
   •   Every UI redraw is heavier
   •   Text and icons cost more GPU time
   •   Any CPU stall becomes more visible

At 1080p:
   •   Same stall exists
   •   Less visible
   •   Often ignored or unnoticed

This is why high-resolution users report it more often.

⸻

Why your system improved so much

Your fixes worked because they:
   •   Reduced Windows GPU queue interference
   •   Stabilized DX11 frame pacing
   •   Removed extra presentation layers
   •   Gave the CPU predictable scheduling

That pushed your system out of the danger zone, leaving only edge-case triggers (map + chat + radio stacked together).

⸻

The key takeaway

The clipboard map is not the cause — it is the clearest reproducer.
The root problem is CPU→GPU synchronization stalls in the DX11 presentation path, which can be triggered by any high-frequency UI or state update depending on system headroom and configuration.

That explains:
   •   Why some stutter without the map
   •   Why others only stutter with it
   •   Why DX9 “fixes” it
   •   Why fixes reduce but don’t fully eliminate it

⸻

What this means going forward
   •   Players without the map open can still stutter → valid reports
   •   Players with stable systems may never see it → also valid
   •   UI stacking makes it reproducible → useful for debugging
   •   Engine-level mitigation is the real solution

So no map, no radio window and probably the system kill messages and anything typed on 200 sounds suspect now..

As I stated earlier, I think the map stutters are a separate secondary issue.

Not exactly a separate issue more they are the quickest way to manifest the root cause.
