FPS Drops?

[Milansta]

For some reason,despite having a decent pc for running doom 3,i kinda experience some fps drops...switched the game to lowest settings still same issues...any solution?

it's irritating isn't it? after all these years not even 1 answer to your question. The only way to fix it is thru observing the frames with an fps counter, and then restarting the game with 63 fps counting at least, on the game's intro. Well........... beside being a crappy engine, from crappy devs. I can say i only play this for my own nostalgia, but to be honest with you, the engine is just crappy as hell

and just 1 more thing that may help you a lot, there's a technology of your cpu, or your MOBO, that is called cpu throtlling, it is used to lower the temperature of your cpu, but if you are abble to keep your cpu cool without throttling it like with an watercooler for example, it would help you a lot not only with this game, but with many others too!

If I had seen this thread in 2016 I would have answered it.

I can confirm that this happens regardless of the age and hardware of the PC. It happened on my old Opteron Dual Core PC using two GTX7300's (I think that's what I was running) in SLI, as well as a GTX 260, and it also occurs on this one which is a Core i7 3770K with a GTX670. It is a bug with the shadow rendering code, and it's extremely noticeable in the docking bay with the Dark Star. What happens is there's a degradation in performance the more shadows enter into the rendering volume. You might start at 60FPS and then have it drop down to about 43. when looking back to the same area - notably the ceiling. Disabling shadows via cvar completely eliminates this behavior and it is the ONLY thing that will.

This particular rendering bug was fixed in the BFG Edition of Doom 3.

You can also try to disable vsync in settings of graphic card's driver. Hardcoded 62.5 fps are purposed specifically for 60 Hz refresh rate and trimming them to 59-60 would can cause stuttering.

I never play with vsync. Its stupid,most games can be capped to 60 fps with a sigle command. Also vsncy has that terrible mouse lag

my problem is different, my problem is that when i let the cpu throtling, it starts throttling right at the same moment when i'm playing the game, and then the frames fall to the values you spoke here, however, when i turn off the cpu throttling, the frame drops just stop definetively

I have my hardware in a massive Coolermaster HAF 932 case with 230mm fans and a monster sized Thermalright Macho heat sink on my CPU. That might have something to do with why I never have problems with CPU or GPU throttling, even though I like to keep my nest at a nice 26.7C ambient. I'm 100% air cooled and I dust the case regularly. Are you playing on a gaming laptop? I know those things can get pretty toasty.

i don't like laptops, except for traveling, the throttling happens when you have no activities on your system, you can see the throttling on your O.S. task manager, it doesn't throttles because your cpu is hot, it throttles because it doesn't detect any app activity on your system, and i know it looks like a very ♥♥♥♥♥♥ technique to cool down the cpu, but you can turn it off on the BIOS of your motherboard, however, i only advice you to do it on your desktop and "NOT"on your laptop, and only if, your desktop have a decent cooling system, like you supposedly described. The throttling may bring the frames down because when it changes the clock of your cpu, it may take a while in a point zero clock till it change to it's programed stock clock again
