Downside of changing "Max frames to render ahead"/"Prerender Limit" to 1/0?
I just got Oblivion, and one of the listed tweaks to make it run better is
to change the Max frames to render ahead (or Prerender limit in Riva Tuner) from the default of 3 to 1 or 0. So I tried it. And it indeed appears to give the FPS a pretty sizeable boost, from about 30 FPS to around 40-45ish. And trying the Sims 2, I also seemingly got a pretty big boost. Are there any downsides to this setting? I can't really seem to find any concrete information on just what this setting does. And most of that seems to indicate the opposite, that it's meant to improve FPS by setting it higher, because the card will render ahead on its downtime. |

Setting the prerender limit higher normally should improve performance, at the expense of possible mouse lag. Could be a driver bug. Do you have VSync enabled? Toggle it and see if the situation becomes reversed. -- "War is the continuation of politics by other means. It can therefore be said that politics is war without bloodshed while war is politics with bloodshed." |
