Grimrock

Posted: **Fri Dec 05, 2014 9:04 am**

Okay, the things I tried tonight were:

- Upgrading to the latest Nvidia drivers. Mine were only a month old but I got the latest November 18th drivers and put those in. Problem still occurred.
- Going into Task Manager and killing every process that I didn't think was needed for basic system services and/or playing the game. Some of the processes came back after I killed them so I left those. Problem still occurred.
- Going into Task Manager and killing processes WHILE the problem was happening. Nothing I killed resulted in the problem going away. All that resulted in the problem going away was waiting long enough.
- Looking for scheduled tasks that happen at regular intervals. Couldn't find any that run on hourly or half-hourly schedules like that. There's a lot of scheduled tasks, and I couldn't do a complete search.
- Looking for a scheduled virus scan setting. There isn't one in the Windows Defender UI, and the Task Scheduler didn't have any triggers set for its scheduled scan option (ie that means there is no scheduled scan configured).
- Just to be sure about the virus scan thing, I actually RAN windows defender and made it do both a Quick scan and a Full scann WHILE I was playing the game. The problem did not occur at that time. So I think that pretty well rules out Windows Defender.
- Leaving the game paused (ESC key). The problem still crops up even if the game is paused, I can see the problem happen in GPU-Z, and if I unpause while GPU-Z is showing the clock dip, then the frame rate is still a slideshow until the problem goes away, just like always. So it's not some specific action I'm taking in the game that causes it. I think this also rules out LUA garbage collection since I wouldn't expect it to try to do garbage collection while the game is paused.
- Setting the Priority of Grimrock2.exe to "High" in the Task Manager. Problem still occurred.
- Obtaining running process lists before, during, and after the problem occurred, for later analysis (see below).

Haven't tried creating a fresh power plan, but I'm skeptical of that one. I've gone through my current power plan with a fine toothed comb and made sure all power optimizations are turned off when the machine is on AC power. However it's my next step to try that one.

Below are the process lists. They were obtained before, during, and after the problem. The differences are:

SearchFilterHost
SearchProtocolHost
splwow64

I suspected the two ancillary Search Indexer processes bigtime, but, here's the thing: Though they are missing from the "After" list, they were present on the "Before" list. I think that rules them out. I think they just come and go all the time.

splwow64 is just the 32-bit thunker for the print spooler. And I wasn't printing anything and I don't have any print jobs queued. I don't really suspect that one. But it's weird that it seems to come and go. Don't know why it comes and goes.

In any case, something I'll need to try is disabling the search indexer and the print spooler services while playing the game, and see if those things make the problem go away. But they shouldn't be culprits I don't think. It wouldn't make sense.

Okay, here are the full before/during/after process lists to satisfy your curiosity (you asked for them earlier):

Okay, I did the following:

- Created a fresh brand new power plan for maximum performance as instructed via the link earlier in this thread, and double checked that all settings in that power plan were set to maximum performance, even the battery power settings.
- Disabled the Microsoft Search service and the Print Spooler service.
- Problem still occurred.

Again, I got before/during/after process lists, and this time, without the Search Indexer and the Spooler to act as red herrings, the list of process names is the same for all three:

splwow64

splwow64 does all the print jobs. It should not run unless there is still a job queued for printing. Is one left in your Printer queues?

Nothing is in my print queues. Right click on each printer and select "see what's printing", and all print queues are empty. Seems that program sometimes runs even when nothing is printing. In any case, it's moot because on my next attempt (the next message in the thread), print spooler was disabled and I still got the problem even without the print spooler executables in memory.

And another factoid: the problem isn't limited to just Grimrock. It's just that I only noticed it on Grimrock because it's more graphically intensive and its frame rate can't keep up if the GPU gets throttled. On other simpler games, the dip isn't noticeable.

I was just playing Marvelous Miss Take (great game BTW), and it's simple enough that it performs the same whether I use the Intel GPU or the Nvidia GPU. Just for ha ha's, I set it to be forced to use the Nvidia GPU. Then I ran GPU-Z while I played it in another window, and sure enough, after about 20-30 minutes, I got the problem: I could clearly see the same telltale dip in the GPU cycles as I had seen with Grimrock. The difference is that Miss Take is not as graphically intensive as Grimrock, so I don't see a framerate hit.

The prior game I played on this PC was Transistor, also not as intensive as Grimrock, but I don't clearly remember if that one slowed down or not. I didn't know about GPU-Z at that time.

So we are looking at a general non-game related problem. Intriguing.

I did a bit more digging regarding "SearchFilterHost" and "SearchProtocolHost". Both are part of the optional "Windows Desktop Search" service which replaces the regular "Windows Search" service on install. I've seen reports that this service can cause both disk and cpu slowdowns; can't tell from experience 'cuz i never installed this optional service.

My take: disable "Windows Desktop Search" service, check if the problem persists and in case it's gone uninstall it.

I'll try looking for that service, but I don't recall seeing two search services. Also, those executables weren't present on my second run, IIRC. I'll double check when I'm back at the pc.

Some googling shows that I'm not the only gamer with this problem. Other folks are reporting similar things with various games and various GPU chipsets. It's usually suggested that temps are the culprit but they are usually talking about temps in the 100c+ range, and GPU-Z isn't showing me anything nearly that high. Still, I'm going to look much closer at temps and see if I can find a commonality.

Yeah, it turns out that "Windows Desktop Search" is just the older name. It's now called just "Windows Search" in Windows 8, and that's the thing I disabled last night... and I still got the problem. http://en.wikipedia.org/wiki/Windows_Search

Today I tried to narrow it down to temperature or GPU loading. I ran two copies of a graphics demo program side by side. The programs maxed out the GPU and memory controller (GPU Load: 99%, Memory controller load: 100%), and this kept the GPU temperature in the 65c-66c range for minutes at a time. The system fans were running at full speed. I couldn't get the GPU temp to climb over 66c no matter how hard I tried. The "dip" never occurred. So if this test is any indication, GPU temperature and GPU load aren't the thing that triggers the issue... I pushed the GPU to the max and that didn't make the problem occur. I'll try again this evening to see if Grimrock can make the temperature get any higher than 66c, but I doubt it will: Grimrock didn't max out the GPU load the way the graphics demo did.

Edit: I looked back in this thread, at the first screen shot I posted of GPU-Z showing the problem. And in that case, the problem occurred at what appears to be 59c or very close to it. So if temperature was the issue, then it certainly would have triggered at 66c when I did my graphics demo run just now. Googling about voltage drops on Nvidia GPUs, it is true that sometimes the voltage will go down if the temp goes up, but the things I read seem to suggest that the voltage cut should only happen if you hit 70c or so. In my case the problem occurred at temps much lower than that.

Okay, over on another forum, someone with a GTX460 is showing a screen shot of GPU-Z that looks identical to mine:

http://www.techpowerup.com/forums/threa ... ps.203498/

The difference is that his card is very clearly showing the PerfCap kicking in very clearly. He seems to think that PerfCap is throttling his card when it hits 77c temp. Which would make sense. But that's not what's happening on mine. In my case, I'm getting the "dip" when my GPU is not at maximum load and my temperatures are much much lower. And deliberately making the chip hit high temps does not induce the problem because I can't even make it go that high.

I still agree that it looks like it's kicking in the PerfCap feature for some reason. I just can't fathom why.

Aha. Aha Aha.

Reading the TechPowerUp forums, it turns out that I need to install GPU-Z and/or do some sort of tweaking to make the PerfCap reason appear. I can't just do the unzip-n-run version. I shall do the necessary steps to get PerfCap to appear and then test again.
