How Do You Set A Frame Limit In PrBoom+?

[Cacaodemon]

I've been using GZDoom to play the vast majority of megawads that I've downloaded, and the source port has worked pretty well overall. I've tweaked settings within it to best emulate a more pure gameplay experience for the various wads, yet I've encountered noticeable performance impacts on a lot of wads released within the past decade and a half, roughly. I'm not sure if it's a matter of of monster count, level size, or something else, but the performance hitches seem to be triggered in settings where there's a long draw distance. As an example, the see through floors of Ancient Aliens, like that of Map 29, would trigger frame drops. Now I've heard that PrBoom+ excels in running more intense wads well, so I recently downloaded it. I tested something like Map 29 of Ancient Aliens in it, and I used idrate to find out that I was getting a couple hundred more frames in this source port than I was in GZDoom. I was very pleased with this performance increase, but there is one issue I still have with the source port. I haven't been able to find out how to manually implement a maximum frame rate limit, like that of 144fps for example. I don't want to be needlessly taxing my computer by having hundreds of extra frames rendered all the time, so I would like to manually set a limit. Does anyone here know if there is a way to do so, either by modifying pre-existing code or writing new code entirely. If anyone could offer some assistance, it would be greatly appreciated.

 

Thanks.

Since PrBoom+ uses it own software rendered, i don't think it would be much taxing for your PC.

Its not hardware accelerated so, you can open the task manager while PrBoom+ is running and you will see that it isn't running wild or having a big impact on performance.

 

I have bittorrent, 12 vignettes of Chrome, PrBoom+ on Sunder map17, and i just have memory use rate of 67%.

I closed bittorrent, and it went down to less than 50%.

You may enable "Vertical Sync" in the "General" menu to adapt the game's rendering rate to your screen's refresh rate. There is nothing more than that to limit the rendering rate, though.
