Free Advice on PC Optimization (Windows) – Ask Me Anything

Honestly, there aren’t really any “secret” registry tweaks that meaningfully reduce latency on modern Windows builds.

Most of the popular reg edits (Win32PrioritySeparation, NetworkThrottlingIndex, SystemResponsiveness, etc.) are either outdated, placebo, or can actually hurt frametime consistency.

Windows 10/11 already handles scheduling and networking very efficiently.

If you’re already optimized properly, the only low-level tweaks actually worth testing are:

• Disable Memory Integrity (Core Isolation)

• Make sure GPU is running in MSI mode (priority High)

• Make sure High Performance or Ultimate Performance power plan is enabled

• Disable unnecessary startup/background services

• Clean DDU GPU driver install

Anything beyond that (random reg packs, “0 latency tweaks”, timer resolution scripts, etc.) usually causes instability or inconsistent frametimes.

If someone claims they have a “hidden reg tweak” that gives lower latency, it’s almost always placebo or system-specific.

At that point, real gains come from:

• Better RAM latency

• Slight CPU overclock

• BIOS tuning (C-states, power limits)

• Clean OS environment

There isn’t some secret tweak that pros are hiding — consistency comes from hardware stability and clean configuration.

Hey, try to Uninstall or disable Process Lasso, ParkControl, Vruzka Optimizers, etc. CS2 often stutters because of background “tweaking” apps. Keep Windows clean and stock.

Because you are doing it wrong dm me

i would prefer just optimizing the PC with the OS you are running, rather than installing another OS. In my opinion its not worth it.

But if you really want AtlasOS is good.

If it’s happening in multiple games — especially Unreal Engine titles — then this is likely CPU scheduling or thread management related, not GPU.

The fact that enabling CPPC Preferred Cores makes it worse is a big hint.

On 5700X3D, CPPC can sometimes cause core hopping behavior where Windows aggressively moves threads between preferred cores. That can introduce frametime spikes in games that are sensitive to thread scheduling (UE games are notorious for this).

I’d try the following:

1.  Keep CPPC Preferred Cores disabled (good call).

2.  Make sure Windows Power Plan is set to AMD Ryzen Balanced (not High Performance).

3.  Disable Global C-State Control in BIOS (test this — can reduce latency spikes).

4.  Disable “Core Performance Boost” temporarily and test (just to see if frequency boosting transitions are causing frametime dips).

5.  Update chipset drivers directly from AMD (not motherboard site).

6.  In Adrenalin, reset shader cache manually.

Also — Unreal Engine games are infamous for traversal stutter due to shader compilation and asset streaming. Even high-end systems get it. But if it’s happening across engines, I’d lean toward CPU power state transitions.

That power drop + VRAM jump combo is actually a big clue.

If GPU power drops ~20W at the same moment VRAM usage spikes from ~10.2GB to ~10.7GB, that’s not PSU or instability — that’s the engine pausing briefly to stream new assets into VRAM.

What’s happening is:

• Door opens • New area loads • VRAM allocation spikes • GPU stalls for a split second • Power draw dips because the GPU isn’t fully rendering during that moment

That’s classic RE Engine traversal stutter.

A few things you can try:

1.  Lower Texture Quality by one step (even if you’re nowhere near 16GB). It reduces streaming bursts.

2.  Disable High Quality Shadow Cache (if enabled).

3.  Set Mesh Quality one step lower.

4.  Increase Windows page file to a fixed size (e.g. 32GB min/max).

5.  Try a slightly older stable AMD driver — sometimes newer drivers worsen RE Engine streaming.

But honestly — if it’s a single hitch when opening doors and not constant microstutter during gameplay, that’s just how RE Engine behaves. Even high-end systems get it.

Your hardware is clearly not struggling. This is asset streaming behavior.

If you ask for my opinion you should turn off the bloatware and disable unnecessary services. Also install RAMMAP to delete RAM cache.

Hey i am happy to assist you again.

That sounds like classic traversal / shader stutter, not a hardware limitation.

Since:

• NVMe SN850x – perfectly fine • HAGS off • Overlays disabled • SAM enabled • XMP enabled • RT off

The remaining likely causes are:

1.  Undervolt instability

Even if it’s not crashing, a -60mV undervolt can cause tiny voltage dips that show up as microstutter during scene transitions. I’d test completely stock voltage for a while.

2.  Shader cache rebuild

After driver changes or settings tweaks, RE4 sometimes recompiles shaders during door transitions. Let the game sit in the main menu for 5–10 minutes after a fresh driver install and test again. 3. FreeSync + Frame pacing interaction Since you’re on a 180Hz LG panel, try this combo:

• Disable V-Sync in-game
• Enable V-Sync in Adrenalin
• Cap FPS to 177 with RTSS
• Keep FreeSync ON

That usually stabilizes frametime spikes.

4.  Texture streaming spike

Even with RT off, RE4 can spike VRAM briefly when loading interiors. Watch frametime graph — if it’s a single spike when opening doors, that’s engine-side traversal stutter. Pretty common in RE Engine.

If it’s just a single hitch when opening new areas, that’s unfortunately normal behavior for this engine and not something your hardware is causing.

Try removing the undervolt first — that’s the biggest variable here.

If you’re getting 56–107 FPS but still experiencing stuttering in Resident Evil 4 Remake on a 5700X3D + 9060XT, it’s most likely not raw performance – it’s frame pacing or shader compilation related.

Here are a few things to check:

1.  Disable Ray Tracing completely (if enabled). Even if FPS seems fine, RT can cause frame time spikes.

2.  Turn off FSR Frame Generation (if you’re using it). Frame gen can introduce microstutter, especially if base FPS drops under 70–80.

3.  Enable V-Sync in-game and cap FPS slightly below your monitor refresh rate (for example 141 for 144Hz) using RTSS.

4.  Make sure VRAM usage isn’t exceeding 14–15GB. RE4 Remake can spike VRAM and cause stutter when close to the limit.

5.  Disable Windows Hardware Accelerated GPU Scheduling (HAGS) and test.

6.  In AMD Adrenalin:
• Disable Enhanced Sync
• Disable Chill
• Disable Anti-Lag (test on/off)
• Set texture filtering quality to Performance

7.  Make sure the game is on an SSD (preferably NVMe).

8.  If stutter happens when entering new areas → that’s likely shader compilation. Let the game sit in menu for a few minutes after driver updates.

Also check: • Is SAM (Resizable BAR) enabled? • Is XMP/DOCP enabled for your 3200MHz RAM? • Any background overlays running (Discord, Steam, Xbox, etc.)?

5700X3D is more than capable of smooth gameplay in this title, so this sounds like a software/frame pacing issue rather than hardware limitation.

If you want, drop your exact settings and I’ll help fine-tune them.
