Things like security and anti-virus software can potentially have a big impact on system performance. Other programs or services running (even when hidden in the background) may be consuming memory and CPU time. Even software updaters downloading and installing things in the background can bog your system down.
In Windows 10, press Control-Alt-Delete on the keyboard, choose Task Manager, click "More Details" (at the bottom), go to the "Processes" tab, and then you can click the "CPU" and "Memory" column headings to sort the list to show you which active processes are taking up the most CPU and memory resources. Clicking the "Performance" tab will also show you the total CPU and memory consumption. Without RaceRender or other programs running, I typically see a total CPU utilization of only a few percent, and the memory used should be less than 1.5 GB (of your 8 GB total). Sometimes there are some spikes in CPU when idle, but it normally shouldn't be high or sustained.
As for things you can do in RaceRender to help the situation, there are a few things you can do:
- Try using the 64-bit version of RaceRender (this tends to be slightly faster, and is preferable on Windows 8 and 10)
- Click the speaker icon to Mute the preview audio
- Click the preview Settings button and make sure that the "Temporarily Reduce Quality While Seeking the Preview" checkbox is enabled
- Click the preview Settings button and choose a smaller picture size
- Click the preview Settings button and choose a lower (ie faster) setting for "Picture Scaling Quality"
