Alt-Tabbing out of the game results in an FPS increase

[PhoenixSpine 0]

First off, I would like to applogize if this is posted in the wrong area, or that this topic has been covered before and that I'm being blind as usual.

Okay, as I play this mod (Or any demanding game), the FPS remains at a high 60 for the a good 10-15 minuites.

After that point, the FPS suddenly drops for a second, only to jump forward as if to replace the missing frames, over and over again.

A quick-fix for this is to Alt-tab out of the game, wait for a moment, then resume. However, I want to know why this happens and how to fix it.

My specs are as follows:

CPU = AMD Phenom II X4 820 Processor Quad Core 2.8Ghz Processor

RAM = 4 GB

GPU = ATI Radeon HD 5670 1GB

Thank you very much for reading.

Welcome to ArmA II... You'll never know

Its strange the game is demanding at all. It shouldn't be, but it's just scripted so poorly, it becomes extremely high edge for what it is.

This happens to any of the recent games I have played (Just Cause 2, Saints Row The Third, Kane and Lynch 2, e.c.t)

2.8Ghz is pretty slow, especially for a quad core, and your 4 Gigs are just barely enough to play most games, if you want them to run as well as they should you should think about getting at least 1 extra gig.

Quad cores are pretty much useless though for Arma 2, as it only uses 2 max.

It's like having space to breath.

Also

Your GPU seems a little slow, even my 4200 has 2 gigs

Ah, thanks for the explaination. I'm planning on upgrading my RAM, but it looks as if I could do with a new rig from the sounds of things.

Many thanks.

I don't know how to answer your question, but we have very similar PC specs and I get lower FPS, I'm using the x3 processor.

What ingame graphic settings you use, and anything to help increase?

This is something that came with the last patch, I'm playing on pretty much the fastest machine you can get and the last patch has been huge with a few things.

- random graphic glitches on both AMD/Nvidia cards around the game, most notably ATC command center in Bolata Airfield.

- random FPS drop, and down to 10-15fps.

My system specs:

- Nvidia SLI GTX 680

- core I7 3930 @4.4ghz ram

- 24GB RAM

- SSD

- resolution: 5760x1080 (triple screen setup)

I think this might help you all. Trying to spread the word because it seriously helped me. I think there is some sort of CPU throttling issues that DayZ and some other demanding games seem to cause. I'm not certain that this fix will work in your specific case, but it sounds like it might.

I had a similar problem. There are many potential fixes cycling around on the forums.

I have an i7-2720QM processor for my mobile pc and it seems to have issues running DayZ mod but not ARMA II itself. I tried about 1000 different optimization tricks. Disabled core parking, took off intel boosting options, changed launch options, etc...

The exact problem I had could be described like this: I can run Day Z mod on the absolute lowest settings or the absolute highest settings and get the same problem either way. It was actually easier to play with much higher graphics settings rather than low settings. The problem was that the game would run great for about a minute or two, and then every 3 seconds or so (sometimes more frequently) the FPS would drop significantly to unplayable levels. I have now discovered that it was probably the GPU or CPU getting too hot and the intel smart boost was backing my CPU off (800 Mhz instead of the normal 2.2Ghz to boosted 3.3Ghz) to more rapidly cool the computer off. Interestingly enough I can set my CPU to run at 1.4Ghz using ThrottleStop and the game runs flawlessly.

I downloaded a program called ThrottleStop by TechPowerUp.

WARNING: Before you use this program read up on how it works. DO NOT just install it and start clicking all of the fancy buttons because it will probably cause your CPU/GPU to heat up extensively if you do not know what you are doing. Luckily most computers shut off before anything bad can happen to your hardware...but be careful and USE AT YOUR OWN RISK!!!

Here is the link to a very helpful ThrottleStop guide:

Here is the download link that I used:

http://www.techpower...eStop_4.00.html

You can use this program to manage the CPU speed and GPU/CPU temps to make the game run more smoothly. Also if you are running a laptop try propping the back of your unit up on a hardback textbook (or get a good cooling pad) because this significantly reduced the heat of my computers components.

Once again, be careful with this program.

Also, it might be nice if someone with authority could make a post about this program (potentially pin it) and the success that it can give users that are experiencing the graphical stutter issues. I can play great using this utility properly.
