Precision M4500 Owner's Lounge

Strange problem. Over the past week, when playing GTA4 things have slowed WAY down. It feels like the CPU is throttled, but I have the power setting to Ultra Performance and it makes no difference.

The GTA4 benchmark used to be around 28-29 fps, and now it is around 15. The game is unplayable.

Can anyone provide hints on what might have happened and how I can fix it? I do remember launching GTA4 recently when I was in a power saver mode. It seems to have not recovered from it.

EDIT: All seems to be better after a second reboot. It was like it never became unthrottled after going into power save mode.

 

Yes - I want to switch my current (1366x768) display with one of the higher resolution displays. Preferably the (1920x1080) but either one will do. Thanks for the response, any advice?

 

That' much better service than we get.

If I recall, you can't mix the two different types (though not 100% sure).

The 1333mhz is better (faster), but quite a bit more expensive.

 

ok ,

the i5 doesn't support 1333Mhz right ?

i7 620m ....can support these frequency ?

here in italy the 1333 are cheaper...

 

Not sure about the ram support issue, I have heard that you need quad cores to support the faster ram. First thread I found discussing it:

http://forum.notebookreview.com/har...arket-upgrades/450403-i7-620m-vs-720qm-5.html

I suspect it supports it, may not use the extra speed though. If 1333mhz is cheaper than 1000mhz though - then probably not an issue.

 

On tech spec of intel's mobile cpu's is info, that core i3-7 dual cores supports max frequeny at 1066 MHz. but quad core runs at 1333 Mhz, so I have in my precision 2x 4GB modul 1333 MHz, but it will be runs at 1066Mhz, look at this and check memory specifications

Intel® Core? i7-620M Processor (4M Cache, 2.66 GHz)with SPEC Code(s)SLBPD, SLBPE, SLBTQ

BTW: I will have my laptop tomorow :-D, so after I got it I can check it. My CPU is Core i7-640M.

 

Unfortunately, I have no advice to give in this area. Hopefully someone else will be able to help you out. I was trying to help gain clarity in case someone else had tried this.

 

when you have news...post it

 

Okay, so I'm trying CS5 on the laptop screen right now. It seems like the effect is not related to the external screen. Happens here as well...

To be more precise: when I have an image open in a subwindow in Photoshop, and I grab the window with the mouse to move it around, the first couple of tenths of a second there remains a "ghost" image of the subwindow in its original location. But this effect ONLY happens right after clicking the subwindow to drag it. That is, if I keep the mousebutton pressed and keep dragging the subwindow around, the delay doesn't repeat itself. But when I release the button, then press it again and do a second round of dragging, it will start with the delay effect once more.

I also noticed that when I ALT+TAB between Photoshop CS5 and other active applications, the Photoshop screen builds up noticeably slower, there is flicker and it is even noticable that the screen builds up component-by-component.

It doesn't seem to matter whether I enable or disable "OpenGL drawing". 64bit vs 32bit also no difference it seems.

These things are not *painful*, but I do experience them as annoying and it makes my M4500 appear much slower than I would like. Perception is important!!

Can anybody with CS5 or other PS version give me his/her impressions when trying this?

I also noticed in the NVidia control panel that the driver has detected "Photoshop CS4". I have "default global settings" in the "Global Settings" tab, and haven't changed anything in the "program settings" tab. But like I said disabling "OpenGL drawing" in CS5 doesn't seem to have influence anyway.

 

Right, I've now been able to reproduce the problem... I think. I opened up loads of images and this time made sure they were all in windows - normally I maximise them and access them via tabs, so it's not possible to have various images all on the same screen - if that makes sense.

Having them in their individual windows, there is noticable lag as you say. Have you tried resizing the windows too? Kind of sluggish like an underpowered 486 machine from yesteryear for me. I don't get the slow build up issue when alt-tabbing. However, I only done tests with fairly low resolution photos loaded (from the Windows 7 "Sample Pictures" folder to be precise).

I don't think it's the M4500, or the graphics card. I think it's just the way they have implemented their custom Windows in PS CS5. The fold out plug-in Windows are slow too.

It might be worth mentioning this on the Adobe forums. I had a google but just found people complaining Photoshop CS5 was terribly slow for panning and scrolling, which I can safely report isn't the case.

I notice Premier Pro and Photoshop are both shown in nVidia control panel as CS4. I don't think that's anything to worry about, even though Premier Pro didn't introduce serious hardware acceleration until CS5 with the Mercury Playback engine. Perhaps nVidia had profiles for CS4 and they're simply not updated the name.

I believe the GPU acceleration only works on the images themselves and their manipulation - the actual windows fall outside of that scope.
