Performance Comparisons

The purpose of this section is to show the results of tests comparing the Skyrim game performance with and without optimization of some of the major vanilla and mod texture sets. It is intended for intermediate and advanced users.

Benchmarking Conditions

Test System

  • Motherboard: Intel DP55KG
  • CPU: i5-760 OC 4.0 GHz
  • GPU: ATI 6850 1 GB (Crossfire2X)
- 1920×1200
- TESV v1.5.26.0
- Driver v12.3 + TESV App Profile

Data Collection

  1. Start GPU-Z, start Skyrim via SKSE
  2. Load savegame1, wait 50 seconds, capture screen
  3. Load savegame2, wait 50 seconds, capture screen
  4. Load savegame3, wait 50 seconds, capture screen
  5. Load savegame4, wait 50 seconds, capture screen
  6. Load savegame5, wait 50 seconds, capture screen
  7. Quit Skyrim, open GPU-Z log
  8. Copy last line - 20 of log block representing savegames (easy to tell in log)
Tested using GPU-Z 0.6.0
NOTE:
Each data row represents the GPU-Z output recorded 20 seconds prior to the end of the 50s benchmark run. This ensures that no anomalies associated with menu access during savegame loading or quitting affected the recording. Waiting at least 25-30s into benchmark runs also allows Skyrim and the GPU to equilibrate to ensure stable and representative values.
