Your target line should look something like "C:\Program Files\Warcraft III\Warcraft III.exe" -opengl

I just realise this line can fix all problem with mouse lag problem faced by so many people who use
optimus and nvidia graphic card.

you mean, the text does not look crispy? i guess better than unplayable mouse lag..haha

yup. i think the frame rate is also much more better. i'll try search around if i can find any solution regarding the crispy text. i ordy try forcing wc3 running in aa mode @ 8x through nvidia 3d panel but only in the menu the text kinda okay. but ingame still crispy. thx again!

really meh. anyway tq for share. i wan try now. how click icon warcraft properties ma then click open gl

i never see any text not crisp.

My setting is:
For nvidia:
vsync off
ambient occlusion = performance
gamma correction = on
multi-display = single display performance
Power management = maximum performance
triple buffering off


actually I dun understand what u talking about.. lol

u can use DiabolicW3Tools to change font.

lolx. i try already liao that bo lag while i play dota. before also lag and now settle problem lag. tq TS

I've already try changing font, still the same. here some screenie about the crispy text. note that the alphabet "i" and "L" look thinner than usual.

you're welcome...glad to help... wat graphic card and laptop you're using?

oic... i never try chatting...hahahahahaha

nvm la about the text. i just wan a smooth gamplay.

i cant seem to opengl my warcraft.. everytime i do so, my warcraft wont open.. it says something like pls insert the correct disc.. -.-"

lol.. i think your copy of warcraft is pirated.

oh dang! really? is there anyway i can fix the lag except through this way -.-"

Why you buy pirated Warcraft?

By the way, your copy of pirated Warcraft 3, you buy from where one?

updating nvidia driver?

i dunno wor...

problem i'm having is, there'll be occasional screen freeze when playing..I dunno what went wrong, but always screen freeze for 1-2 seconds, then continue again de.. @@

how to fix??
i'm using Asus A42Jr graphic ATi Hd 5470..

force your laptop to HIGH PERFORMANCE in power gear...

prob still same..huhu

If ur gpu doesnt hve problem running in normal mode, then just play with normal mode. since opengl mode only for those who have problem wit mouse lag. did u encounter any mouse lag too?

Radeon GPU with switchable GPU suffers the same problem too.
Laggy mouse.

Bad thing is, Radeon GPU does not run opengl.
Good thing is, you can disable switchable GPU in bios.

Disable the switchable GPU will solve the issue.

rite now my prob fix after i've updated Ati catalyst..version from 10.5 to version 10.10
no more prob..thanx for give opinion

huh? ATI not running opengl? now that's new thing I learn today....

seems like ATI and nVidia directX old driver is broken.... but is fixed in the latest driver...
weird that both solve it at the same time

Yes, ATI does not support opengl by default.
It requires separate driver.
http://support.amd.com/us/kbarticles/Pages...iew-driver.aspx

It is not the old directX problem.
This is because changing to from "switchable" to "discrete" would solve the laggy problem. The driver works fine.
It is generally the driver problem for the "switchable" and "optimus".

I dun get what u meant...

Optimus works fine for all other game with latest directx. Only Warcraft 3 with older directX not working.

Also, by using openGL, switchable/optimus driver works fine... proof that no problem with Optimus/switchable.

Only problem is with DirectX driver.

If you search around the internet, even nVidia newer graphic card have mouse lag.. so definitely not Optimus
issue. But a generally compatibality of DirectX 8 vs nVidia driver.

It is the "driver for optimus" problem, especially you can't turn on the discrete GPU.
You can't run in discrete mode with optimus.
As I said, even Radeon with "switchable" suffers the same problem too.

There is no problem for discrete GPU like GT330 to run Warcraft3.
I never had laggy problem with GT330.

It is a driver problem but it is not the directX problem.
GT330/GT335 use the same set of driver.
It is a "driver for optimus" problem.

if cannot turn on discrete GPU, meaning it'll use i5-450 CPU which is more than enough for
Warcraft 3. So mouse lag is not that it cannot turn on discrete GPU right?

GT330 no mouse-lag issue.
I turned on the discrete GPU on my 3820TG & 4820TG and the mouse-lag issue was gone too.

So, the possibility is current drivers do not run well in hybrid mode.
They need better drivers.

well, current hybrid mode driver is running well from someone who updated their driver. No need
to run openGl....

probably hybrid mode problem...

gogo
now i know the main prob is when i'm playing a dota without using battery then the prob coming..huhu..
still confused wat the prob

sometimes when i'm using battery with ac mode the prob start...uhhh
but when using battery only nothing happen..i can play dota smooth...

u know what prob is?

It could be buggy bios. Or corrupted system.
Try updating the bios and re-install OS.

erm, normally if AC mode and Battery mode will affect your power configuration. Did you check what
you set if AC mode and what you set during Battery mode?

i set ac mode same as battery mode(high performance) n the prob still same..huhuh
any idea??

you can try ALeUNe's method since my easier method not really the problem.. hehe...

becareful updating BIOS...

I would recommend format and install new OS first before doing the BIOS...

sorry for late reply..
ahaha...after i've update my bios from ver 402 to ver 504 the prob is solve..so i can play game smoothly
thanx guy for recommend the solution =)

thanx gogo & aleune
