With fallout 3 i could only play it properly with the Render ahead limit set to "0" in the nvidia control panel. If it didnt play it with it set to 0 the game would literally play at about 10% speed and would take forever to do anything, that is, if it didnt crash before hand. After setting the option my game became extremely playable.

Now i want someone else to test this in fallout New Vegas. I have been playing with it set to 1/2/3 to no good results, even though the game is playable for me at either setting though with apparent frameskiping issues. Though switching it to 0 has done the trick for me, completely removing microstuttering and frameskipping issues.

If your wondering how to set the option or cant find it, right click on your desktop background and click Nvidia control panel, under manage 3d settings under global settings, or if you want to be really tricky, do it for the specific game so no conflicts will result in other games, go down to Maximum Pre-rendered Frames and boom there you are.

I believe its a problem because it seems to be conflicting with the games built in frame skipping.

But i want others to set it to 0 and see if there is any difference. In fact use it with all the other "Fixes" and post back results if you could.


also if your using an amd gpu go ahead and switch the setting to see if it helps for ati...uhh AMD users. Note that the setting is named differently.

I assume you have a Nvidia video card?

I have a Nvidia 250 1gb card. Before the current 260.99 and d3d9.dll one of the first things I did was set prerendered frames to 0. It did not help at all. Only thing that really improved the stutter was the d3d9.dll. The 260.99 driver fixed the white flashing Boxes I was getting from having AA on (Only set at x2).

It is true that I also had prerendered frames set to 0 in Fallout 3 for the stutter issue. However, doing so in Fallout New Vegas showed no improvement at all. Fallout 3 runs Great. Fallout New Vegas has many of the same issues as Fallout 3 - but more severe. In addition to this - it has outrageous clipping issues along with many new bugs.

For me - only the .dll work around - made this game playable.

the dll fix did nothing for me though. im on a gtx 260, only a step higher than yours and the only things that has helped me was to change the limit to 0 and type "toggleemotions" in console to remove most of the npc lag, nothing else has helped me beyond that. i can now get a solid 60fps or more, dropping whenever some things are streamed into the game.

oh and i noticed that gpu usage shot up for me when i set anti-aliasing on to 4x, before without it my gpu rarely went past %50 and hovered around 20-30s before i set the limit, now i will see it shoot up to 90 at times but constantly stay over %50 now.

the vast amount of differences people are experiencing with this game is just laughable.

just tested the dll fix again, it actually gave me huge pauses when moving my mouse at all. so thats out of the question still
