Optimizing your framerate.

Introduction

Racer contains some features to perform profiling. Although not as detailed as what you can do with a compiler, this does give an idea of what Racer is spending time on.

General profiling

The 'debug 6' screen contains a number of profiling items which shows where Racer is spending time. You'll probably notice most time being devoted towards graphics, especially shadow map creation.

Graphics profiling

With nVidia cards you can also check a few internal counters. These counter names are exposed by the driver so may vary from card type to card type, and with driver revisions. To get these running:

• Install nVidia's PerfKit. I've had best luck with Windows 7; on previous versions I had lots of trouble getting it to work.
• In racer.ini, set dev.nvidia_perf to 1 to enable performance counters.
• Also set dev.nvidia_perf_path to the location of of nvPmApi.Core.dll. For example C:/packs/NVPerfKit/bin/win7_x86/NvPmApi.Core.dll
• Run Racer and enter 'debug 6 1' to see some PerfKit counters.
