your GPU is probably running capped right now and you've never known about it
there's a setting called Resizable BAR (NVIDIA) / Smart Access Memory (AMD) that lets your CPU access your full GPU memory at once instead of in tiny 256MB chunks — and most people have never turned it on
free FPS. no downloads. takes 5 minutes. here's the full guide:
CHECK IF IT'S ALREADY ON
🟢 NVIDIA — right-click desktop → NVIDIA Control Panel → System Information (bottom left) → look for "Resizable BAR" → if it says Yes you're good
🔴 AMD — open Radeon Software → Home dashboard → bottom left → "Smart Access Memory" → if it says Enabled you're good
if it's off or missing, keep reading
HOW TO TURN IT ON — BIOS
restart your PC → press DEL or F2 as it boots to enter BIOS
→ find "Above 4G Decoding" → enable this FIRST
→ find "Resizable BAR" (NVIDIA) or "Smart Access Memory" (AMD) → enable
→ make sure CSM / Legacy Mode is OFF
→ Save & Exit → reboot
if Windows won't boot after doing this, your drive is formatted as MBR instead of GPT — search "convert MBR to GPT Windows" it's fixable in 10 mins with no data loss
VERIFY IT ACTUALLY WORKED
🟢 NVIDIA — back in Windows, NVIDIA Control Panel → System Information → Resizable BAR = Yes ✅
🔴 AMD — Radeon Software → Home → Smart Access Memory = Enabled ✅
still showing disabled after BIOS changes? update your motherboard BIOS firmware GPU drivers to latest. that fixes it 95% of the time.
DOES YOUR GAME BENEFIT? real breakdown:
✅ Fortnite — yes, open world asset streaming hits different with this on
✅ Warzone — yes, massive maps mean constant VRAM transfers, this smooths it out
✅ Apex Legends — yes, meaningful FPS gains reported across multiple setups
✅ Black Ops 6 — yes, CPU-heavy engine responds well
✅ Battlefield series — one of the strongest use cases, big maps destruction engine = big gains
✅ Valorant — marginal but no reason to leave it off
⚠️ Rainbow Six Siege — test it yourself, some benchmarks show a slight performance drop on this specific title. turn it off if your frames get worse.
WHO THIS IS FOR
✅ RTX 30 or 40 series GPU
✅ RX 6000 or 7000 series GPU
✅ Intel 10th gen or Ryzen 3000 CPU
✅ Motherboard with a BIOS update from 2021 or newer
❌ GTX 10 or 16 series — not supported
❌ RX 500 series or older — not supported
❌ Laptop users — check your laptop manufacturer's support page, it depends on your specific model
❌ nothing breaks from checking — if your hardware doesn't support it, the option simply won't appear
this is the one setting that's been sitting in your BIOS doing nothing while you spent money on thermal paste and RGB fans
costs $0. takes 5 minutes. works tonight.
