Clean AMD → NVIDIA Flow
  • DL TOOLS Download DDU + NVIDIA Driver — while still on AMD
  • NETWORK OFF Disconnect LAN / Wi-Fi — before every cleanup step
  • AMD CLEANUP Run AMD Cleanup Utility in Windows → Reboot
  • SAFE MODE DDU Safe Mode → DDU → GPU: AMD → Clean and Shutdown
  • SWAP CARD Install RTX after shutdown — stay offline
  • DRIVER Custom → Clean Install → Reboot → then reconnect network
AMD Cleanup removes gfx/audio — DDU Safe Mode prevents leftovers during swap.
Smoothness Baseline
Monitor LG 34GN850P · DP · 160 Hz OC · Adaptive-Sync ON · FAST
NVCP Sync G-Sync ON · V-Sync ON · Power = Prefer Max Perf
In-Game V-Sync OFF · FPS Cap = Refresh −3 → 157 @ 160 Hz
Low Latency ON (Baseline)
Reflex-Games NVIDIA Reflex use in-game
Overlay NVIDIA App → FPS · 1% Low · GPU/CPU util · Latency live
Canonical Stack: G-Sync + V-Sync ON in NVCP · V-Sync OFF in-game.
NVIDIA Tools
FrameView Avg FPS · 1% Low · Frametimes · Power · Perf-per-Watt
CapFrameX Best Frametime Analysis / 1% Low — repeatable
Afterburner + RTSS: Fan Curve · OSD · FPS Cap · Volt/Freq Tuning

NVIDIA App Driver-Mgmt + Overlay Metrics
Prof. Inspector Advanced per-profile tuning — use with caution
NVSlimmer 3rd-party Slim Install — conservative expectations

5070 Ti — Curve & Validation
START POINT
~900 mV
@ ~2650 MHz
ZIEL
Efficiency-first
not Max Boost
  • GOAL Fewer power spikes → cleaner frametimes overall
  • TEST 30–60s same scene → Avg FPS · 1% Low · Frametime Graph
  • REGEL ✗ avg FPS↑ but Frametime Quality↓ = Tuning failed
Validierung in echten Games — nicht nur in Synthetic Benchmarks!
Top Fails
✕ No FPS Cap → frame queue grows → no fluid feel
✕ Wrong Sync Combo → tearing, lag or uneven pacing
✕ HDMI instead of DP → can limit refresh / VRR behavior
✕ "Faster" Overdrive on LG → overshoot / dirty motion
✕ Going online too early → Windows injects its own driver
Game Notes
◈ Warzone / DX12: Reflex ON + Boost als Baseline.
◈ Keep DLSS/FG changes separate from driver changes.
◈ Spiky CapFrameX frametimes → fix pacing first.
◈ PUBG / Stalker 2: Reflex + CapFrameX · Cap bei 157 FPS.
02POST-INSTALL · WRAP-UP · CHECKLIST
Post-Install Checks
1. Device Manager: correct GPU, no stale display adapters remaining.
2. Remove leftovers: C:\AMD · C:\Program Files\AMD · C:\NVIDIA
3. Clear cache: %localappdata%\NVIDIA\DXCache + GLCache
4. Re-check refresh rate and G-Sync after driver install.
5. NVIDIA App Overlay: GPU Clock · FPS · Latency verifizieren.
Notes
Sheet prioritizes practical smoothness over benchmark FPS chasing.
NVSlimmer is 3rd-party — not an official NVIDIA utility.
References: Vendor docs and current project pages.
Canonical Sync: G-Sync + V-Sync ON (NVCP) · V-Sync OFF (in-game).
Sheet favors practical smoothness — not synthetic benchmark FPS hunting.
