fps tanks during firefights

[Qwertion]

It goes to 20. Used to be allright back when I bought it. Anyway to fix this?

Two possible causes are the lights from gunshots, and the combat ai from multiple npcs bogging down the engine.

There's nothing but the brute force of hardware to deal with the latter.

The former can be adjusted with a mod.

My pc is not old. I'm able to play skyrim special edition on ultra settings with barely any slutter. That probably has something to do with windows 10.

You'd be surprised at how irrelevant that is.

Creation 2.0 made a lot of improvements in performance that are actually noticable in SSE because the content is from a five-year old game. In my experience it does run better than the original. (Comparably, Fallout 4 runs awful due to a complete disregard for the limitations of the engine and DX11. One step forward, two steps back is the bethesda motto.)

The version of Gamebryo that New Vegas runs on is considerably less effecient. It uses the CPU for more or less everything. Gun fights with multiple participants exacerbate this issue significantly.

Pro tip: the argument of "My game can run Game X on supermegaultra8k+ settings at 9763123 fps" stopped meaning anything about 12-15 years ago. I suggest to stop using it, as I could show you a 19-year-old game that I guarantee would stutter and lag on your system. Skyrim uses a different engine, so it will run differently.

As for your predicament, the game's performance depends on the single-thread performance of your CPU, nothing else. AMD FX chips and hyper-threaded Intels (i3/i7) before Skylake can and sometimes have problems with that, so the game's framerate can take a dive on those chips.

Anyways, back in the day when the game just released I could play it on max settings with no problem. The only things that are different today - I have a superior graphics card, 4 times more RAM than I used to have and new OS. My CPU is the same it was when the game ran perfectly.

are you even reading what people are saying? it's the game engine, you could have Quad GTX1070's, 64GB of DDR4 3200Mhz, and a i7 7700k and you'd still see performance issues, same idea as in Skyrim, the game is capped to 60FPS and anything over causes problems with object collision and geometrics due to how the engine works, people using GTX 980ti's sometimes have troubles getting a solid 60FPS, because like any other game your FPS will drop in high pop/spawn areas, as well as big cities, and during intense combat.

as to why this is just now happening, maybe you just started using an FPS monitor, and you notice FPS drops more, or maybe you have mods that require more horsepower or maybe your even using IWS or another mod that adds more enemies to the game. I started playing Fallout NV on a XFX HD 5750 and was getting almost 60FPS with exception of during firefights, and upon upgrading to my R7 260x 2GB OC (a 45% increase in performance over the HD 5750), I was getting near 60 all the time, but when using IWS and NPC spawner my FPS would drop to the 30's even when not in combat.

In summary check your mods, and understand it's the game engine, not your hardware.

Also newer hardware sometimes does not work as well with older games.

I am reading what people are saying. That's why I said my CPU stayed the same. I bet your last sentence is on point. Most likely it's windows 10. It's hard to play now unfortunately. Wish I could play the dlc at least once, though.

[Bansheebutt]

Game runs fine on W10 for me, ftr.

By the way, how do you measure frame rates? If it is not Steam's built-in one, then the measuring itself has a huge impact on it, ironically, because of the overlay most likely.

It's steam built in one. Why would I use a 3rd party one.

[talgaby]

Because many people still are stuck with Fraps or just like Afterburner too much.

And did you make sure to delete your old ini files when you got the new video card? You need to do that because your video card info is stored in the file. The game might be thinking that you are still using your old card.

It doesn't think it's my old card, yet, now that you mentioned it, it says it's 7900GS. If that's one of those that were before the 3 digit card series started, it would certainly be a viable explanaition. I have GTX 780 Ti. It doesn't seem to be anywhere near auto-detected series. I thing I did a clean reinstall of the system, when I got it, though. Where could check whether I have old ini files or new ones?

[Qwertion]

Never mind that, it's because of d3d9.dll it seems. Will check, if it's the cause whenever the game agrees to launch.

[talgaby]

If it thinks it is a 7900GS, then you are using the old and obsolete NVidia DLL fix, probably because you installed it because of the recent Win10 issue.
