Periodic stuttering in DirectX 11 games is commonly tied to shader cache corruption, driver overhead, or Windows presentation stalls.To resolve or minimize DX11 micro-stutters:Increase or reset your Shader Cache size. For Nvidia, expand the shader cache allocation to 10 GB+ via the Nvidia App graphics settings; for AMD, clear and reset the shader cache within AMD Software: Adrenalin Edition after driver updates.Disable Multi-plane Overlay (MPO) in your Windows registry or via display configuration toolkits if presentation hitches persist.Cap your Maximum Framerate slightly below your monitor's refresh rate using third-party utilities like RivaTuner Statistics Server to smooth out frame pacing inconsistencies.Toggle Hardware-Accelerated GPU Scheduling (HAGS) on or off in Windows Graphics Settings, as it handles memory management differently per system architecture.Perform a clean driver installation using Display Driver Uninstaller (DDU) to clear out residual shader dumps or conflicting files.Watch this video for a demonstration on optimizing your shader cache size and reducing micro-stutters:1mBest Micro Stutters & FPS Drops FIX For ANY Game (Windows 10/11 Guide)2.7K views · 1 month agoYouTube · The Software GuyIf you want to narrow this down further, let me know:Your GPU model (Nvidia, AMD, or Intel)Whether the stutter happens continuously or only when entering new areas/loading effectsAces High Bulletin BoardDX11 Micro Stutter Fix!!!

Well, it seems like it's fixed, thank you HT!!!, and I guess this sort of proves the theory, I didn't do any of the above, just launched game like I always do and watched netstatus for 20 mins, no stutter, this means I can get my FFB stick back out of the cupboard, the stutter meant the stick lost connection to game output if I was manouvering during the stutter, and crashed the game.
Woohoo!!
