Kelmych's System Specs

Benchmark conditions: STEP 2.2.1 Guide

The following table provides means ± standard deviations for 4 parameters being used for system benchmarking with STEP mods.:

  • GPU temperature
  • GPU load
  • Dedicated VRAM (on-card memory) - This caps at 2 Gb on my system.
  • System VRAM (swapped-to-system memory) - lower is better, I am still determing the value at which moderate/severe stuttering on my system
  • FPS

In addition, the table includes two additional parameters, the maximum dedicated VRAM use and maximum dynamic VRAM use during the benchmark test. The reported values are the maximum of a five second running average of dedicated and dynamic VRAM, and are provided since they assist in building conclusions about the test.

Prior to running the benchmark tests all of the Vanilla textures (textures in Skyrim - Textures.bsa) were optimized using DDSopt as discussed in the DDSopt Guide. Selected STEP mods were also optimized prior to the test. The selection used the STEP Mod table from the DDSopt guide. Any mod with at least one Yes in the first 4 columns was optimized using DDSopt. Note that this did not include any of the large environment mods in the Conflicting Graphics section of the STEP guide as the authors of these mods have already done substantial optimization of their textures. The mods used were those in the STEP list with one exception. Instead of using only Skyrim HD and Serious HD, a mix of textures selected from 5 mods were used to provide the textures that these two mods would have provided. The additional mods used are Skyrim Realistic Overhaul, Langleys Wood Metal and Stone Workshop, and Riften HQ. The specific textures included were the ones Cestral chose from these 5 mods for Texture Pack Combiner.


(z's conclusions - mine are not here yet) Notice below where the standard deviation (SD) is rather large for Dedicated VRAM when there the VRAM usage is at peak efficiency (operating at near maximum capacity). However, the SD quickly goes down as available VRAM shrinks. This is because VRAM from second to second has nowhere to go but down, when it previously had room to get much higher OR much lower. As Dedicated VRAM SD decreases, this should correspond to an increase in swapped (System) VRAM, which should beget stuttering or lag in gameplay.


As the GPU becomes VRAM taxed:

  1. FPS goes down
  2. Mean-dedicated VRAM consumption increases
  3. Mean-dedicated VRAM SD increases at first and then decreases as if fills to capacity
  4. Mean-system VRAM increases
  5. Mean-system VRAM SD increases rapidly as it is relied upon in varying degrees and then decreases as it fills to capacity (or the swap capacity of the GPU)

At the point that the System VRAM SD begins to noticeably decrease, stuttering should become significant, as this indicates a very high swap frequency.] Template:Notice Small
