no other choice than wait direct x,not sure about performance,but it will surely help people with "window has stopped working problem",some may resolve it by updating driver and some may not...intel make no sense.

You're right, I just confirmed it with Henrik, and 2.0 cards will work mostly, but are still screwed if the emulator calls 2.1 functions for certain games. It's a borderline situation.

I'll update the main post now.

EDIT:- I also just realised that the baseline should be 2.0, since the Radeon X series also works just fine with PPSSPP, with only a few lingering issues (like in GTA that other cards don't have) and it doesn't support 2.1 either.

So, to summarize, the baselines for all 3 vendors are as follows.

NVIDIA:- 6xxx series minimum (2.1 support)

AMD:- X series minimum (X300+, 2.0 support)

Intel:- GMA 3000 series minimum, with the right drivers.

I don't think that you are right here. X-series supports upto OpenGL 2.1. If you don't believe me then just take a look at the screenshot provided below with the use of OpenGL Extensions Viewer. Even that damn ancient X300 supports 2.1 , which means those cards that came after X300 such as X800, X1300 etc supports OpenGL 2.1 as well.
   
That's a different case though, if some extensions of 2.1 is broken in those GPUs such as ARB_pixel_buffer_object which permits buffer objects (PBO/FBO) to be used not only with vertex array data, but also with pixel data. Also, GTA VCS uses Motion Blur all the time which is an FBO effect after all, that makes a lot of sense to me why the current implementation of those extensions in PPSSPP breaks GTA VCS for those GPUs. Anyway, drivers of ATI/AMD always seems to be inferior as compared to their rival e.g, Nvidia.

Interesting.

So the wiki must be wrong then, since it claims ATI's X series only supports up to 2.0.

The drivers could support 2.1, but does the card ITSELF support all of 2.1's extensions?



This means that the X series is NOT fully 2.1 compliant in hardware, which is what I meant in my initial statement. The version exposed to the hardware is 2.1, but the hardware itself is only capable of ALL 2.0 extensions.

Here, look at this example provided from AMD themselves, even THEY state that their BEST X series cards are only fully 2.0 compliant:-

(This is the official spec page for the X1950, which was the TOP of LINE card for the X series)

http://www.amd.com/us/products/desktop/g...tions.aspx



The same Extension Viewer application says that the DirectX version supported is 9.0c, but we damn well know that the X300/X800 series ONLY supports up to DX9.0b in hardware.

Interesting. I think you are right. I always thought that it supports OpenGL 2.1 as per Extensions Viewer, so thanks for the correction. I'm seriously starting to loose respects for AMD. Btw, does most Android devices supports OpenGL 2.1? I've seen some Android users reporting Black screen on GTA VCS.

[TheDax]

Mobile devices use OpenGL ES 2.0(and 3.0 in newer devices), an entirely different beast.

[The Phoenix]

Ah my little Android phone is a Armv6, uses according to the system info built into PPSSPP (A great feature BTW thanks) states mine uses only OpenGL ES 2.0 Extensions. so it seems I don't have ES 2.1.

Funny enough my PC also only has OpenGL ES 2.0 Extensions.
Yet I don't have many issues with that.
So my conclusion is what others are saying, its something to do with AMD/ATI graphics cards that's causing problems.

[TheDax]

There is no ES 2.1.

OpenGL 2.0 isn't the same as OpenGL ES 2.0, and OpenGL 2.1 is also not the same as OpenGL ES 2.0.

[VIRGIN KLM]

Either way systems that aren't actualy able to use any of the current versions of OGL they are 100% not capable/suitable for PSP emulation at all so it's not really worth discussing if your system just barely meets the OGL 2.1 requirement, these systems are so outdated that PSP emulation on them is a no go route.

The point of this thread is just to make a one stop place to point to in other threads when folk come around asking about the issue.

That is all.

Also the same reason why I made the performance guide, I got tired (and I bet others forum contributors are too), of answering the same questions over and over again from 1 post driveby junior posters who only ask that question and leave, never to be heard of again.

This way we can just link them, saving time and effort that could be better spent in other more useful efforts with regards to the emulator.

I know but I think the best thing you can do for this is make a section on PPSSPP's homepage that clarifies such stuff and then create a rule that restricts people from making such questions which will mean problem solved.

well if it wont work, on my laptop thats only 2 years old, what good is it. im done on this emu then, no gold purchase for them.

[TheDax]

If you want someone to blame, blame Intel. It's not our fault they have crap support for OpenGL.

[sowonforever09]

the "ppsspp has stopped working" doesn't appear on 0.76

[Thefreak121]

Hey I'm not sure but I have an intel graphics card and ppsspp emu used to work on my pc on win 7 but when I upgraded to Win 8 It then said that I don't have open gl 2.1 , I'm confused since it did work before, my chipset for my laptop is: mobile intel ® 4 series express chipset family. Will the ppsspp emu work on this chipset? Pls reply asap.

i think you need to update your gpu driver firstly
