Testing conducted on hardware featuring an AMD Ryzen 7 9800X3D processor and an MSI GeForce RTX 4070 Ti GAMING X TRIO 12G graphics card shows that while image quality remains consistently high across settings, frame rates vary by up to 11.8 percent.
DLSS 4.5 DLAA Performance and Visual Benchmarks
When operating in Deep Learning Anti-Aliasing (DLAA) mode at 2K resolution with maximum graphics settings, the upscaler’s presets K, L, and M deliver virtually identical visual fidelity.
Despite the visual parity, performance metrics differ across the three configuration profiles:
- Preset K: Delivers a reference frame rate of 34 FPS, offering the highest performance among the DLAA options with a stable, flicker-free image.
- Preset L: Yields a frame rate of 30 FPS, marking an 11.8 percent performance drop compared to preset K while maintaining identical clarity.
- Preset M: Records a frame rate of 32 FPS, representing a 5.9 percent decrease from preset K and a 6.7 percent increase over preset L.
Hardware Constraints and Testing Methodology
The hardware configuration used for the evaluation included 32 GB of DDR5 6200 MHz RAM and a Samsung 970 EVO Plus 1 TB NVMe SSD. Testing was restricted to 2K resolution rather than 4K to isolate the upscaler performance from engine-level memory conflicts. When physical memory runs low, the engine blocks rendering threads completely rather than dynamically reducing asset quality, necessitating 2K benchmarks to prevent texture streaming errors.
Additionally, ray casting was disabled during the benchmarking process because the technology does not currently function alongside DLSS 4.5. The comparative analysis indicates that users prioritizing raw frame rates in DLAA mode can select preset K for a minor performance advantage without sacrificing visual stability.
