Fastish camera flicks downward have inconsistent frame timing / poor motion clarity despite high FPS

The game runs at high FPS (240+ FPS), but the movement with the camera feels off. It was never like this before. I tried every single setting. Yet it still feels off. After GDK came out I had issues for around 6 months then it was fixed for like 3 months now its back. It's uneven instead of smooth. When performing fast camera movements in Minecraft, the game does not feel playable. Normal looking around is fine, but quick flicks (like looking straight down to place blocks quickly and then flicking back up) create a noticeable frame quantization visual effect that feels similar to a VHS motion blur. I can just tell something is off when placing blocks and bridging and moving the mouse around quickly. Your game is not smooth or optimized. The motion appears inconsistent. It feels like the frames are not being displayed evenly, creating a strange "stepped" or "uneven timing" effect rather than true low FPS. Given I have this feeling even if I'm at 1000 to locked at 240 FPS. Smooth motion and ultra low latency in Nvidia settings seems to mask the problem a bit. But this is overall unplayable and the amount of things I have done to try and fix it is astronomical and upsetting.

CPU: AMD Ryzen 7 7800X3D

GPU: NVIDIA RTX 4070 Ti SUPER 16GB

RAM: 32GB DDR5-6000

Monitor: 2560 x 1440 240Hz

Steps to reproduce

Use a high refresh rate monitor. (240hz)

Launch Minecraft Bedrock.

Move the mouse quickly while looking around.

Perform rapid competitive movements (fast downward flick → place blocks → fast upward flick).

Observe the motion consistency.

Some of the things I've done that i remember probably a lot more that I don't remember:

1. Reinstalled/Updated NVIDIA drivers

2. Updated AMD chipset drivers

3. Tested NVIDIA Control Panel settings:

4. Power Management Mode: Normal/Maximum performance

5. Low Latency Mode: On/Off

6. Tested VSync ON and OFF

7. Tested HAGS ON and OFF

8. Tested Xbox Game Bar ON/OFF

9. Disabled background recording

10. Checked Game Mode settings

11. Disabled Dynamic Refresh Rate

12. Disabled Enhance Pointer Precision

13. Reset Windows using Reset this PC → Keep my files → Cloud download

14. Tested on a fresh Windows installation

15. Installed Windows updates after reset

16. Checked startup programs/background processes

17. Tested different FPS caps

18. Tested different refresh rates (240Hz)

19. Disabled overlays:

20. NVIDIA overlay

21. Xbox Game Bar

22. Disabled background recording

23. Reinstalled Minecraft

24. Cleared Minecraft cache

25. Changed:

26. Render distance

27. Simulation distance

28. Graphics settings

29. Input response

30. v sync in options.txt

31. Tested different USB ports (including motherboard rear ports)

32. Disabled USB selective suspend

33. Checked BIOS settings

34. Checked RAM settings (DDR5-6000/XMP/EXPO)

35. Checked CPU/GPU usage and temperatures

36. Confirmed hardware is not being fully utilized during issue

37. Tested MSI Afterburner/RivaTuner and found frame pacing issues

38. Windows Performance Recorder Testing:

39. A Windows Performance Recorder trace was captured while reproducing the issue on a bedrock server.

40. Findings from Windows Performance Analyzer:

41. CPU usage did not show signs of CPU saturation.

42. Minecraft was not maxing system resources during the issue.

43. DPC/ISR analysis showed activity from:

44. dxgkrnl.sys (DirectX graphics kernel)

45. nvlddmkm.sys (NVIDIA display driver)

46. USBXHCI.SYS (USB controller)

47. ntoskrnl.exe (Windows kernel)

48. HDAudBus.sys (audio bus)

49. rt68cx21x64.sys (Realtek driver)

50. The trace suggests the issue may involve frame presentation/timing, the graphics pipeline, or driver/input interaction (probably not) rather than insufficient hardware performance.

51. Additional observations:

52. FPS remains high.

53. GPU/CPU utilization is normal.

54. The issue is most noticeable during rapid camera flicks and competitive movement.

55. The system previously felt smooth before the issue appeared.

56. And the camera movement is still bad and off on a flat world with low render distance on a Ryzen 7 7800x3d and a 4070 ti super

57. Checked BIOS settings:

58. SVM

59. CSM

60. Boot settings

61. PBO settings

62. RAM profile

63. Booted into Windows Safe Mode to perform a clean GPU driver removal using DDU (Display Driver Uninstaller)

64. Used DDU to remove NVIDIA display drivers completely

65. Reinstalled NVIDIA graphics drivers after DDU cleanup

66. Installed/reinstalled the latest AMD chipset drivers

67. Tested the system after the clean driver installation

68. Checked ping/network conditions on servers

69. Removed/uninstalled MSI Afterburner/RivaTuner after testing

70. Tested without unnecessary background applications running

71. Checked for Razer GameManagerService3

72. Checked uepmaster.exe/background processes

73. Tested Microsoft Store Minecraft install/reinstall

74. Cleared/rechecked Minecraft-related cache files

75. Tested on a flat world with extremely low render distance to rule out world generation, entities, server load, and rendering complexity. The issue remained.

76. Checked and modified relevant Registry (Regedit) settings while troubleshooting before the windows reset

77. Ran Windows system integrity checks and repairs using SFC and DISM commands. No change to the issue after repairs.

78. Tried different scaling options, display/GPU.

The problem is most noticeable during fast mouse movements and competitive camera flicks.

Normal slow camera movement is mostly acceptable, but when performing quick movements (for example, flicking the camera downward to place blocks and immediately flicking back upward), the motion feels off.

The camera movement feels different compared to how the PC originally performed. On a high refresh rate monitor, rapid movements should appear smooth, but quick flicks have an uneven visual feel even when:

• FPS is high

• The world is simple

• Render distance is low

• CPU/GPU usage is normal

• The issue is especially noticeable during:

• Fast downward flicks to place blocks

• Quickly looking back up

• Rapid PvP camera movements

• Quick mouse direction changes
