High p99 frame times in OW2
Hello, I've been debugging this PC for quite some time, and am stumped.
First, here's my user benchmark: https://www.userbenchmark.com/UserRun/73118878
Second, here is a representative CapFrameX capture of what I see as a problem:
Here is my HWiNFO:
CPU: AMD Ryzen 7 7800X3D (Raphael, RPL-B2) 4200 MHz (42.00x100.0) @ 4850 MHz (48.50x100.0)
Motherboard: MSI MAG B650 TOMAHAWK WIFI (MS-7D75)
BIOS: 1.P0, 04/23/2026
Chipset: AMD B650 (Promontory PROM21L.1)
Memory: 32768 MBytes DDR5 SDRAM @ 3000 MHz, 36-36-36-76
- 16384 MB PC48000 DDR5 SDRAM - Corsair CMK32GX5M2D6000C36
- 16384 MB PC48000 DDR5 SDRAM - Corsair CMK32GX5M2D6000C36
Graphics: ASUS TUF RTX 4070 Ti GAMING OC
Drive: Samsung SSD 970 EVO Plus 2TB, 1953.5 GB, NVMe
Drive: Samsung SSD 980 PRO 2TB, 1953.5 GB, NVMe
Sound: NVIDIA AD104 - High Definition Audio Controller
Sound: ATI/AMD Zen APU - Display HD Audio Controller
Network: RealTek Semiconductor RTL8125 Gaming 2.5GbE Family Ethernet Controller
Network: MediaTek Wi-Fi 6E MT7922 (RZ616) 160MHz Wireless LAN Card
OS: Microsoft Windows 11 Home (x64) Build 26200.8328 (25H2)
Here is what I've tried, in no particular order:
- New CPU (Intel -> AMD)
- RMA'd my GPU ("repaired" and returned)
- Tried a friends GPU (2070 super)
- Swapped PSU
- Moved game to another drive
- Update BIOS
- Update SSD firmware
- Better windows power profile
- Disable HAGS
- Disable Game Mode
- Disable Core Protection
- Disable memory compression
- MemTest (no errors)
- Unplugged all USB peripherals except a controller
- New monitor (older ASUS to newer PG32UCDM)
- Turned off EXPO
- Slight OC on CPU
- Studio driver
- Run with no background software
- Fresh windows install
- DDU
- Gaming on Linux
- Turned off all power saving features in my Ethernet controller
- Turned off bluetooth
No matter what, I get stutters like in the above graph.
