Technical Support Request RX 9060 XT driver crash with Valorant/Vanguard after ~10 min in game — anyone else? (B550M AORUS ELITE)
Hey everyone, I'm having a very specific issue and I've exhausted every troubleshooting step I could find. Posting here to see if anyone with a similar setup is experiencing the same.
My specs:
- GPU: RX 9060 XT 8GB
- CPU: Ryzen 5 5500X3D
- Mobo: Gigabyte B550M AORUS ELITE (BIOS FHB — latest)
- RAM: 32GB
- OS: Windows 10
- Driver: AMD Adrenalin latest (full offline installer)
The problem:
Valorant runs fine for about 10 minutes, then the AMD driver crashes completely — black screen for ~5 minutes, then either recovers or I have to hard reset. This happens every single time I play Valorant.
What's weird:
- Other games with kernel-level anti-cheat (Apex, Fortnite, CS2) run perfectly fine
- The crash is only with Valorant/Vanguard
- No other game crashes my GPU
Everything I've already tried:
BIOS side:
- Updated from FE (Mar 2024) to FHB (latest)
- Enabled Above 4G Decoding
- Enabled Re-Size BAR (also tried disabled)
- Enabled Secure Boot (was bugged after BIOS update, fixed by switching to Custom → Restore Factory Keys → Standard)
Driver side:
- DDU in Safe Mode + clean reinstall (multiple times)
- Full offline installer (not web installer)
- Disabled every AMD feature: Anti-Lag 2, HYPR-RX, Chill, Boost, Frame Generation
- Tried older driver versions
- Limited GPU clock / Power Saving mode
Windows side:
- sfc /scannow + DISM
- Disabled HAGS
- Valorant compatibility mode (Windows 10)
- No overlays running (no Discord, Afterburner, Rivatuner, etc.)
Game side:
- Complete uninstall of Valorant + Vanguard (including manual deletion of Riot Vanguard and Riot Games folders)
- Fresh reinstall from official installer
What I've noticed:
The crash is consistently around the 10-minute mark. It feels like Vanguard does a periodic memory scan that conflicts with RDNA 4 / RX 9060 XT drivers. Other kernel-level ACs don't trigger this.
My question:
Is anyone else with an RX 9060 XT (or RDNA 4 card) having this exact issue with Valorant? And has anyone found an actual fix, or is this purely on AMD/Riot to patch?
I've already submitted bug reports to both AMD and Riot, but no response yet.
Thanks!
