Hey folks,
With the transition to EA Forums, bug reports have gotten a new post type that better helps us track and update the status of issues, among other things. The new forums should be much ki...

I asked ChatGPT about this:
Changing resolution in FPS games (e.g., from 1080p to 4K or vice versa) can definitely impact aim and ADS (Aim Down Sights) stability, for a few technical and perceptual reasons:
1. Mouse Sensitivity Scaling
- Resolution impacts how many pixels your crosshair moves per mouse input unit (e.g., DPI × sensitivity).
- At higher resolutions (e.g., 4K), your screen has more pixels, so small mouse movements result in less crosshair travel on-screen.
- If your game or system doesn’t scale sensitivity correctly (e.g., raw input off, or affected by resolution), aiming can feel slower or “heavier.”
Effect: Feels like you’re under-aiming or over-correcting; hard to make micro-adjustments in ADS.
2. FOV (Field of View) Changes
- Some games scale FOV with resolution, especially if tied to aspect ratio.
- A wider or narrower FOV alters how targets appear and move on screen, which can affect how you perceive and track them in ADS.
Effect: Tracking and target acquisition feel inconsistent when changing resolutions.
3. Input Latency Differences
- Higher resolutions (like 4K) demand more GPU power. If your FPS drops even slightly, input lag increases.
- Even a small change in latency can disrupt fast reflex aiming or ADS precision.
Effect: Aiming feels “delayed” or less responsive at higher resolutions.
4. Perceived Mouse Acceleration or Inertia
- Lower frame rates at higher resolutions may introduce micro stutters or inconsistent frame pacing.
- This results in a perception of inertia or “floatiness” in your aim, especially in ADS when slower movement is required.
Effect: You might miss flicks or overcorrect tracking movements.
5. Pixel Density and Target Size
- At higher resolutions, enemies are rendered with more detail but smaller relative size unless UI scaling compensates.
- This makes precise aiming harder, especially at long distances or in ADS.
Effect: You feel like your crosshair “jumps” past targets or it’s harder to line up shots.
6. ADS Sensitivity Scaling Not Matching
- Some games separate hip-fire and ADS sensitivity, but don’t scale ADS sens properly with resolution changes.
- If ADS sens becomes too fast or too slow due to scaling mismatch, your muscle memory breaks.
Effect: Your ADS feels unstable or unpredictable at a new resolution.
7. Monitor Response Time and Scaling Effects
- If your monitor has scaling hardware or switches refresh rate modes between resolutions, this can affect motion clarity.
- Ghosting, blur, or overshoot may be more apparent at certain resolutions.
Effect: Visual instability while aiming or tracking.
Quick Fix Suggestions:
- Enable raw input in settings.
- Match in-game FOV across resolutions.
- Use mouse sensitivity calculators (like DPI Wizard) to adjust for resolution/FOV differences.
- Lock frame rate to a stable value (e.g., 144 FPS) and enable G-Sync/FreeSync if available.
- Use lower resolution + upscaling tech (e.g., DLSS, FSR) to maintain clarity + performance.
Since you’re using the Xbox Elite 2 controller on an Xbox Series X, here’s how changing resolution (e.g., 1080p to 4K or vice versa) can affect aiming and ADS (Aim Down Sights) stability specifically for controller players:
Stick Sensitivity Feels Off (Resolution + Perception)
- Controller stick input is mapped to camera rotation, not pixel distance.
- However, how far the camera appears to move visually is affected by resolution and FOV.
- At 4K, movement may feel slower or more “draggy”; at 1080p, movement may feel snappier.
Effect: Your ADS aim may feel inconsistent or unpredictable when switching resolutions.
Field of View (FOV) and Zoom Perception
- Some games tie FOV to resolution or aspect ratio (if not locked manually).
- A wider FOV (common at higher res) makes targets appear smaller and move faster.
- In ADS, this can cause over/under-aiming due to target size distortion.
Effect: You feel less precise or consistent in aiming down sights.
Input Latency from Resolution Demands
- Higher resolutions (especially 4K) push the GPU/CPU harder, potentially reducing frame rate or increasing latency.
- Even if FPS is technically the same, higher latency slows the response time between stick input and camera movement.
Effect: ADS feels sluggish or “floaty,” especially in fast-paced fights.
Aim Assist Behavior (Subtle but Real)
- Aim assist relies heavily on frame rate and visual smoothness to track targets.
- At lower frame rates or higher latencies (from high-res settings), aim assist may feel stickier or laggier.
- The controller’s behavior through the aim assist bubble can change subtly depending on visual clarity and stability.
Effect: You feel “off” when snapping to targets or tracking in ADS — like the aim assist isn’t helping consistently.
Visual Clarity and Pixel Density
- At higher resolutions like 4K, enemies are smaller and sharper, but you must be more precise when aiming.
- At lower resolutions, targets are larger on-screen, so fine stick movements feel more forgiving.
Effect: ADS stability suffers because your thumb movements don’t translate the same across resolutions.
UI & Crosshair Scaling
- Some games don’t scale UI/crosshairs properly with resolution changes.
- If your crosshair or ADS reticle becomes smaller or less clear at 4K, it affects your visual reference for aiming.
Effect: You’re less confident with micro-aim corrections in ADS.
Monitor/TV Scaling & Response Time
- Some TVs or monitors introduce input delay or visual processing (like oversharpening or motion smoothing) when switching to higher resolutions.
- This adds to latency and may reduce motion clarity — especially visible in fast-scoping or tracking in ADS.
Effect: Aiming feels imprecise, especially when trying to flick or track targets.
Optimization Tips for Controller Players:
- Prioritize frame rate over resolution (e.g., Performance Mode instead of Quality Mode in-game).
- Turn off TV processing features (e.g., motion smoothing, dynamic contrast).
- Use a monitor/TV with low input lag and 120Hz support if possible.
- Customize your controller curves (Xbox Elite has software for this) to maintain consistent response in ADS.
- Calibrate dead zones carefully—higher resolution can exaggerate minor drift or twitchiness.
