Welcome screen is lagging in VAIO S 15

Hi,
I got my new VAIO S 15 (Core i7, RAM 12GB, SSD, Nvidia 2GB), I noticed the graphic is little lagging at the screen after the welcome screen, there is fading but it is happening slow, everything else is fine so far.
It should not happen in Nvidia 2GB.

I'm using Speed mode.

Anybody who has VAIO S 15 running into that kind of issue?

 

I get that sometimes after a boot, all other transition effects are lagging too (opening/closing/minimizing windows etc.). I haven't bothered much with trying to figure out why it's happening, a reboot seems to fix it.

 

I don't have lagging in (opening/closing/minimizing), only in Welcome fade effect, and reboot didn't fix it
What's your graphics score in Windows index?

 

Keep a couple things in mind:

(1) Your discrete GPU will ONLY be used for graphically-intensive (generally 3D) applications. Even if you select it in the NVIDIA utility as the preferred device, you can't FORCE Windows to use it. On other machines (e.g., Lenovo Y470) you could do so, but not on the Sony. In other words: it's not being used for general desktop/system animations.

(2) AFAIK Windows Experience Index can't see the 640m. The score you're seeing is for the Intel HD 4000. I haven't seen any evidence yet that anyone can get it to work in WEI. If you're curious about how your card is performing use a utility like GPU-Z, MSI Afterburner, or a graphics benchmarking app.

(3) The lagginess you describe sounds exactly to me like it's a CPU issue, caused by services/processes loading at startup. You might consider going into Computer Management and switching non-essential service to "Manual" rather than "Automatic" to give you a little more zip at startup!

I may agree with you in point 1 and 2.
But in point 3, I'm not sure, I don't have any software, my system is still clean.

 

Please elaborate -- clean = wipe/clean reinstall, or "clean" = fresh out of the box?

-Matt

 

I tried both, I noticed this when it was fresh out of the box, then I tried to install a clean Windows 7 and installed all drivers only (no software), problem persists.

 

ARGH, really? I was betting it was a software issue. Guess you killed that hypothesis!

Hmmm, feel like tinkering with msconfig and try selective/diagnostic startup?

I have this problem before,but I do the following

in Nvidia Control Panel>Manage 3D settings

Preferred graphics processor : High-performance NVIDIA processor(When you switch to Stamina,it will change to Integrated graphics)

in Settings > Antialiasing - FXAA > Select "ON"

 

I set 'High-performance NVIDIA", but actually I can't find Antialiasing - FXAA in Nvidia Control Panel Settings

 

I'm not sure whether the Graphics scores is based on Intel or Nvidia, because I seems to have the same scores on both. (can Intel HD4000 scored 6.9?)

But I'm very sure we can test it in both manually.

Right click on command prompt and run as administrator, then type 'winsat d3d'.
This will run the graphics assessment, and will provide you with the result at the end.
I can also select from nvidia control panel to run intel or nvidia by manually adding the winsat.exe file.

Here are the results :

Intel HD4000


GT640M LE STOCK (500/900)


GT640M LE BIOS MOD (1000/1000)

 

I agree and the same thing puzzles me. I should have been more agnostic about my WEI answer!

Thanks, that was AWESOME!

Thanks for info, I did winsat d3d ang I got almost your numbers, check image attached.
But that winsat.exe only fix WEI score, but doesn't fix my slow motion Welcome, do you have slow motion Welcome?
