PvZ GW2 crashes immediately after launching

The first digit in the old Radeon number system was for the generation, not the performance level, and an "N450" is a very low end video device, lower than some Intel onboard video chips these days.  It is also relatively elderly, whatever performance level it might have been.  Neither of the highly publicized "check" sites are particularly accurate. 

The SR Lab website is the worst of the two.  It is wrong so often, the place is just a very bad joke.   I also have seen some errors on some GPU Boss comnparisons, although not this time.

Note that after the game was finalized, AMD ceased to offer driver updates for the HD 5000 and HD 6000 GPU generations, so a substitute, the HD 7730, has been suggested.

Thanks for the reply.

So, it is a GPU problem? Then what do you propose and can you guide me?

If you are here in the states, or in Canada, you can shop at Newegg, for some decent prices on GPUs plus the matching power supply (the stock one is almost certainly too small).

No i'm from the Czech Republic, i know the stores with PC components there.

So you're saying that there is no other solution then buying a new and better GPU?

You'll need to avoid the games that were developed using the Frostbyte game engine, such as PvZ: GW2, and stick to low intensity, simple games to suit the low end hardware. 

And which AMD GPU should i look for then? Any, that has the last three numbers higher than 750? I guess it should be HD, so that it is compatible with my desktop

Since the HD 6000 generation (February, 2011), we've had the HD 7000s, the Rn 200s, and the Rn 300s, and those HD 7000 cards are getting hard to find now. 

This outfit offers to ship almost anywhere, and $83 for an HD 7750 looks like a good deal for a minimum card . .   http://www.aliexpress.com/item/Original-Desktop-Graphics-Card-Radeon-HD-7750-1GB-GDDR5-128bit-DirectX-11-HDMI-DVI-DisplayPort-512SP/32496670826.html?spm=2114.40010308.4.2.I59RCY

I named one in Newegg's catalog that will do the job.  The R series cuts the numerals to three, with only the last two for performance.  You'd need an R7 370 or an R9 360. 

Well, i found the solution, it was the last possible thing i could do, apart from buying a new GPU

I found this as the final update for my drivers. After installing, the game launched, although it has like 15-20 FPS even on low settings, so i have to play it in window mode, but at least i can finally play the game.

Hi,

I am having the same issue and have the below video card on a laptop;

Is this not good enough too?

Thanks,

Wayne

The HD 8500M / 8700M is roughly 20 to 25% slower than the minimum desktop Radeon required.  It may run the game at very low screen resolutions, and with most quality settings as low as they can go.  Its performance may be slow, but the crashing has some other source, such as drivers.
