Low fps. Need help.

[x Princess Leliana x]

I recently got back into this. I installed (among other things) fellout, project reality, nmc's texturepack (large) and the enhanced shaders enb. With all these on i played at around50+fps untill i got to nipton. At this point the game dropped to around 20fps and stayed there. Thinking it was nmc's pack i downloaded and used the medium, and then small versions, none of these worked above 20fps. I then disabled all graphical mods, and im still getting a constant 20fps, its not a problem with my hardware as i can run games like metro last light on maximum settings at 50+fps.
Any ideas what the problem is?

EDIT: I believe its a problem with Nipton itself, i fast travelled to a few different locatons and got solid 60fps, back to nipton and i get 20.

too much mods?as always :)

My guess: smoke and fire shaders. But it's only a guess.

Every computer setup has a set of certain locations in New Vegas that drop the fps. It's somewhat random (some people have trouble with certain areas, others are experiencing this in entirely different cells), but places like the NCRCF interior, Nipton, McCarran, Sierra Madre, Freeside and the Strip usually kill the frame rate. A lot.
Nipton (and the Madre) is usually trouble for AMD video card owners, since those cards always had more trouble with smoke and particle effect than nvidia ones.
Also, keep in mind that ENB itself can randomly drop fps when it suddenly wants to render a lot of different things at once, and you cna only disable ENB by deleting all files, including the New Vegas INI files, and letting the engine re-detect hardware and reset all options.

If i were to remove one thing to help overall performance (im getting 2 pretty much everywhere now) what would you suggest? Is removing the enb gonna be themost successful option? If so how, ive checked all the enb's readme's and the mod page, there are no uninstallation options.

[x Princess Leliana x]

removed the enb and ran fallout using the 4gb launcher, no change in performance.

ENB is sort of a hit and miss. It's probably the thing that kills your rig the most, but it's usually a better idea to get rid of in-engine enhancements like Redesigned before you remove ENB. Strangely though running mesh and texture mods can be safe, as long as you can keep them small in size and in file number. Usually for examply running BnB Type armor replacer (full) with update clutter meshes and Poco Bueno + NMC small + EWI's additional textures has almost negligeble effect on performance, as long as you have at least 1 GB of VRAM and 6 GB of RAM.

this is ♥♥♥♥♥♥♥ ridiculous, i have disabled EVERY graphics mod i have, i have turned aa and multisampling off in the launcher, and have set texture detail to medium, and im getting on average less than 35 fps, LESS THAN 35, on a pc that can run metro and bioshock infinite on max at solid 60 fps. To make matters worse, if i turn or move it drops to 10. WHAT THE ♥♥♥♥ IS GOING ON

The fact that you can run <insert name of shiny FPS game here> means little to nothing for New Vegas for two reasons.

One is that FPS games usually put heavy emphasis on graphics, and they use graphics engines that can adapt to GPUs easily. Plus since most cards are benchmarked with FPS games, both manufacturers optimise their drivers for them.

The second is that New Vegas doesn't give a *beep* about your muscle-rig, it's limited by the CPU's single core performance. (If you don't believe me, run a process explorer that is more sophisticated than the built-in in Windows one, and you'll see that it puts load on the first core, and some on the second.)
So you can have a quad SLI/Crossfire rig with octa-core CPU, this 15-year-old engine will still use only one processor core, and most modern CPUs suck at single-core operations to the point that current AMD CPUs– despite being a really excellent line of products, and I use them with great satisfaction– are usually outclassed by 5-yo i3s or even Pentium IVs in this regard. (And Intel CPUs aren't that juicy in this department either.)

Granted, you can help it a little by using the Stutter Remover's initially disabled feature and replace heap so the game does use a secondary core in a more efficient manner, but the good heap replacement algorithms only work on some CPUs.

i did some stuff, got the game (this is all without mods) to 60fps, opened a door, it stopped and went back to around 20-30, after a while, it stabilised and i got between 40-60 with occasional (once every 3 or 4 secdons) drops to 20, only problem is, the game (even on 40+) is stuttering a lot, jumping/skipping frames, does anyone have a fix that can get this to stay at 60 fps. Before installing graphics mods, i could play the default game with maxed out settings at solid 60, now, even after removing all mods, it wont get to that even on the lowest default settings.

the game also freezes at random intervals, yes i have the fallout stutter remover.

bump, still need help.

You have the stutter remover? Try editing the ini (located in Data/NVSE/Plugins). From the readme:

Master\bReplaceHeap: (defaults to 0, consider changing to 1)
This is still off by default because some people experience instability with it. Turning on heap replacement does improvement performance though. The amount it improves performance by depends upon how much multithreading your copy of the game tries to do - if it tries to do a lot of multithreading then this setting can produce really huge improvements. This also helps with some serious performance issues that arise in longer game sessions when playing a heavily modded game on Windows XP. If you have trouble with Master\bReplaceHeap turned on then you might try different heap algorithms by changing Heap\iHeapAlgorithm, which should usually be either 6, 5, 4, 1, or 3.

I used to get choppy performance as well, this fixed it for me.

thanks, ill try it, im putting the game (default game, no graphics mods) back to ultra (this is what it defaults to when i detect my hardware) lets see if this works.

cant find anything to edit, when i search for "Master\bReplaceHeap" in the "sr_New_Vegas_Stutter_Remover.ini", this is what it comes up with "_comment =This section is disabled by default - see Master/bReplaceHeap", reading on it says that the entire section is disabled, but doesnt give instructions on how to enable it, could you be more specific please?

[Jules]

It's in the section "Master", at the top of the ini. You will see a setting for "bReplaceHeap" on the 7th line or so.
