offcial intel 2361 frivers they offer on site have significant performance improvements. minimum 25% performance gain in all games. up to 50% in many titles. Also many graphics glitches in games fixed. all marked in readme file. I would call this significant. latest intel drivers 2462 is even better.

 

lol, and with new intel drivers throttling issue is much harder, guess why? ^__^

Thanks for your response.
Then it would be very curious for me why isn't lenovo shipping this model with the 90w adapter originally.

Intel Download Center has
8.15.10.2361 dated 04/13/2011

Lenovo supplies Intel HD driver
8.15.10.2342 dated 03/25/2011   [less than a month older]

Intel Release Notes list performance increases over version 2266,
which is much older than the Lenovo-supplied Intel HD driver.

In other words:

 1. Lenovo supplied HD driver is not "very very old".

 2. Intel driver is not likely to increase WEI significantly.

In addition, the Intel Driver Update Utility does not recognize HD graphics in the X220,

making use of the Intel drivers a needlessly risky proposition. From the Intel FAQ:

"I know I have an Intel device but the Intel® Driver Update Utility does not recognize it?
Intel provides generic versions of software and drivers. If your computer manufacturer altered the features, incorporated customizations, or made other changes the Intel Driver Update Utility may not recognize the device.
Please contact your computer manufacturer for the latest updates and technical support information."

Presumably because the 65W adapter is much smaller and lighter, and does the job in the great majority of real world situations, making it a good fit for an "ultraportable" machine. I think most customers would prefer the 65W adapter if given a choice, but I do think Lenovo should give them that choice when configuring the system, instead of making them buy the 90W adapter as an extra accessory.

JNavas, i have no idea what are you talking about.

my personal experience that with 2418 driver i got performance bust in Fallout New Vegas is about to 40%

to compare with 2342. (before minimum fps was 23 with new drivers 32)

In NFS Shift with 2342 minimum fps was 17 with driver version 2418 is 27. etc.

 

all you said above just bla-bla-bla. you trying discuss in topic where you have no idea whats going on.

simple enjoy your very old driver. 2342 have only one advantage it doesn't throtle so much as 2418.

We'll just have to agree to disagree. What I posted are facts. No call to be rude. Have a nice day. :)

intel graphics drivers through lenovo update is very very old

try install new ones like 2418 or 2430


Why does it take a month or more for Lenovo to repackage Intel's drivers? I'd be happy if Lenovo just provided the Intel drivers as-is if they're going to take so long re-zipping them and typing up a useless "read me" file.[1]

On a side note, I haven't noticed any slow down graphically. I haven't run any benchmarks (other than WEI) but when I play my FPS games, they seem to work fine with decent frame rates. Sure does get hot near the exhaust port though.[2]


[1] Less than a month is actually a short time by industry standards. The reason is that Lenovo is responsible to all its customers, including enterprises that purchase large volumes of machines, and can't afford to rush out drivers with minimal benefits that might create huge issues for its customers. Lenovo probably does its own testing of drivers in its own systems, which takes time, and some delay also allows for feedback from other users of Intel drivers. You can tell early adopters by the arrows in their backs, and Intel drivers are notorious for issues and bugs.

 

[2] This kind of minor driver update will tend to have little or no benefit in the majority of applications, so unless you have a specific issue the driver addresses, it's best to wait.

"

go to intel.com site then in the search box at very top right corner type 2430 or 2462

then there will be drop down list appears and first string there will be 2430 for example

point your mouse cursor there and you will see popup menu at left from your cursor

choice there "drivers and files" -> and you will go to secret intel drivers ^__^

 

they will give you some nice fps gain in games. up to 50% to compare with lenovo preinstalled drivers

 

but there is 2 problems

 

1st. Install these drivers a little tricky.

a. download new drivers

b. turn off your internet connection

c. go to device manager find intel drivers and delete it (mark checkbox include soft)

d. reboot

e. Windows will start trying install drivers - cancel it

f. Install your downloaded drivers

g. reboot

 

2nd problem in brighteset. you will notice that your dispaly is twice brigther than before

to reset it back to default lenovo states run regedit and find Key called 'FeatureTestControl' value will be f800

replace it with f940. find next. replace all. REBOOT.

 

enjoy.

"

-> Hi @ all. Im from Germany and I had problems with game performance so I was reading this thread for weeks now.

Right now im very happy because the text above helped me a lot to gain more FPS in many games. 25-50% wasnt a lie. JNavas, you rely on facts and I like that, but in this case Bender957 was right. It may depend on what Driver you had installed before, in my case it was the newest Lenovo driver.

I also tried installing a new one with device manager "search for new drivers" - that worked but nothing improved.

 

In fact I gained like +20 FPS which is quite a lot. Thanks @ Bender957 for the guide.

 

I dont want to restart the "fight" and throw new unproofed material among you guys but I tested benders hint and it worked for me.

 

All in all, Intel Turbo boost+ still doesnt work on my device. I turn it on, the fan makes some noise but performance and CPU-frequency keeps the same.

CPU-Z shows 2998 mhz and sometimes 789 or something. I never reach 3,2GHZ. Also lenovo performance tool shows GPU staying at 100%, instead of rising to more.

 

Long story short : Bender gave a nice Tip to improve game performance, throttling issue isnt fixed anyway so all of us, including the happy +20fps guy (me) will wait for the BIOS update announced until the end of the month.

 

Some info : I have X220t (IPS) 4GB ram, Win7 pro 64bit and most important : Core i5

 

ProzessorIntel(R) Core(TM) i5-2520M CPU @ 2.50GHz7,1
4,7
  Ergibt sich aus der niedrigsten Teilbewertung
Arbeitsspeicher (RAM)4,00 GB5,9
GrafikIntel(R) HD Graphics Family4,7
Grafik (Spiele)1696 MB insgesamt verfügbarer Grafikspeicher6,2
Primäre Festplatte17GB frei (126GB gesamt)7,4



Hard Disk score was some time at 7,8 ( ;D ) due to my OCZ Vertex 2 160GB SSD. (lenovo uses samsung?)

 

Graphics just rised from 6,1 to 6,2 . That migth just be a "bug" or tolerance from windows performance index (or how it was named in english ;) )

 

- Score just did not change a lot, but performance in games inproved a lot :)

 

Oh and I used 2430 driver.

 

Kai

Ok, so the X series (X220 I7, intel SSD) is "NOT" a gaming laptop!  I run multiple Virtual Machines for development without any throttling and this is on both battery (my modified power setting) and AC (standard 90 watt charger) both with Turbo (the battery handles my air time).  Whoever thought an ultraportable was a gaming machine may have been smoking an illegal subsance (well U.S.)!

if this allow plays games with comfortable fpd and graphics detail why this is "NOT" a gaming laptop? no, srsly, why? ^^

 

games just a kind of computer applications. they should work if hardware allow it. and shouldn't throttle anyway
