As a sanity check in preparation for the 2.09 release article, I tested performance for the original "Return to the City" map.
I probably should have been more exhaustive but I wanted to get through it today.
Starting with TDM 1.02: 24FPS 1080P 4xAA 8xAF Bloom
TDM 1.03: 21FPS 1080P 4xAA 8xAF "HDR-Lite"
TDM 1.07: 23FPS (same settings as 1.03)
TDM 1.08: 25FPS (same settings as 1.03)
TDM 2.0: 27FPS (same settings as 1.03)
TDM 2.03: 26FPS (same settings as 1.03)
TDM 2.05: 28FPS (1.03 settings, uncapped FPS)
TDM 2.06: 32FPS (1.03 settings, multi-core, uncapped FPS)
TDM 2.06 GLSL (no soft shadows): 26FPS
TDM 2.07: 46FPS ( 2.06 settings, GLSL enabled, FBO enabled )
TDM 2.08: 49FPS ( 2.07 settings + Bloom )
TDM 2.09: 51FPS ( 2.08 settings )
TDM 2.09 with Soft Shadows and SSAO: 32FPS
TDM 2.09 with 2.08 settings plus Soft Shadows, SSAO, and r_fboResolution 0.7 64-bit color 45FPS
I probably should have tried a lower resolution and uncapped FPS but there are some clear progressions here.
This mission is sort of stubborn with performance gains compared to others due to the visportal issues.
I also should have compared it to Return to the City v2 etc.
Looking back, we probably should have made a bigger deal about the performance jump in 2.07.
Edit: For comparison TDM 1.07 RTTC v2 = 72FPS (someday engine improvements will catch up to mapper optimizations...)
