Fixing shader compilation stutters on Manli Star Ship RTX 5090 D?
It's honestly stressful when you have top-tier gear and still see frames tank from 140 down to 40 during a firefight. My Manli Star Ship RTX 5090 D v2 OC 24GB was boosting past 2.5GHz, but the shader compilation queue was getting backed up, causing response times to swing wildly between 30 - 50ms. I tried DLSS to boost the raw numbers, but it introduced some annoying ghosting that just made me more irritable. I ended up nuking the entire shader cache folder in the driver directory and manually set the NVIDIA shader cache size to 10GB. Once the re-compilation finished, frame times snapped back to 7 - 10ms, and that buttery smoothness finally returned. The first time I cleared the cache, the game took three minutes to load, which was a nightmare until I disabled my real-time antivirus scan. Now, VRAM usage is steady at 18.2 - 21.5GB and core temps are a chilly 55 - 62℃. 3DMark loops prove the drops are gone, and the input lag is virtually non-existent.
