Shadow of the Tomb Raider: Still the Best DX12 Benchmark Config

The objective is to utilize the “Highest” preset as a base but manually toggle Ray Traced Shadows and DLSS/FSR to isolate the hardware’s raw compute vs. tensor performance.

1. The “Clean” Benchmark Baseline

To get a scientifically repeatable result ($R_{repeat} > 99\%$), you must disable dynamic features that interfere with raw frame delivery.

SettingRecommended ValueTechnical Purpose
DirectX 12OnMandatory. DX11 in SotTR is heavily single-thread limited and unoptimized.
Anti-AliasingSMAAT2xProvides the best balance of edge clarity without the heavy blur of TAA.
Ray Traced ShadowsOff (for Baseline)Turn OFF to measure raw rasterization; ON for “Next-Gen” stress testing.
DLSS / FSROffKeep at Native resolution to measure the GPU’s true fill rate ($R_{fill}$).
V-SyncOffEssential to prevent the monitor’s refresh rate from capping the data.

2. Analyzing the “Bottleneck” Percentages

The 2026 build of SotTR provides a “GPU Bound %” metric. Understanding this is key to your upgrade path:

  • 99% GPU Bound: Your GPU is the absolute bottleneck. Increasing your CPU speed will result in 0% FPS gain.
  • <50% GPU Bound: You are heavily CPU limited. This usually happens at 1080p with a high-end card. Your GPU is “waiting” for the CPU to send draw calls.
  • The “Sweet Spot”: For a balanced high-end rig, aim for 85-95% GPU Bound. This ensures your GPU is fully utilized while leaving a small amount of CPU “air” for background tasks.

3. High-Precision “Stutter” Detection

SotTR’s benchmark is divided into three scenes: Cozumel (Market), Cenote (Cave), and Hidden City (Paititi).

  1. Scene 1 (Market): Tests CPU crowd simulation and draw call density.
  2. Scene 2 (Cave): Heavily tests GPU lighting and volumetric effects.
  3. Scene 3 (Hidden City): The ultimate “CPU Torture Test.” If your frame-time graph shows massive spikes here, your RAM Latency ($t_{CL}$) or L3 Cache is the likely culprit.

4. 2026 Pro Tip: The “Ultra” Secret

The “Highest” preset is actually not the highest the game can go. To truly max out a modern system for a benchmark:

  • Manually set Shadow Quality to Ultra.
  • Enable Screen Space Contact Shadows.
  • Set PureHair to Normal (High often causes unnecessary physics glitches that skew the results).
