Couldn't it be a session time limit? Has happened to me several times after being logged in for a while.

Can you do that in Zandro? Why don't you quit using F10 or ALT+F4?
What is a GP? :roll:

It's "GP..." not "GP" (as in speaking half the sentence before realizing that it's pointless.)

Hello guys
I tried to run PB with the maximum settings for the game and the LZDoom port itself on the computer. Intel g3220. Video card-Nvidia gtx 750ti-2gb. Everything works perfectly.
I didn’t have any problems even on an old computer with GZDoom. The video card was Nvidia geforce 9600. Some processor from AMD (I don’t remember which one already)
And the laptop had performance problems in GZDoom (HP Pavilion g6 2316er)

For the record, the oldest fully supported cards for GZDoom 4.x are the Geforce 8 series, which are the oldest GL 3 cards that have a working driver. There should really be no need to resort to LZDoom on those. I had a Geforce 8600 until 2012 and aside from huge levels performance has always been more than adequate. Of course it won't be happy with something like Frozen Time... ;)

Why does the AMD video card have poor performance in GZDoom and LZDoom and does NVIDIA have no problems with this?

How do I properly configure a crappy AMD graphics card for maximum LZDoom performance?

It's a driver problem. Submitting a single draw call takes 20x as long on AMD as on NVidia. Since executing the draw call takes a lot less time on modern hardware, all that time is just lost.

So it was not Grand Prix neither Graphic Processor. :)

I had an 8400 GS but i had to exchange it for a radeon x1500 since it was a crappy cheapo brand (POV) and picture quality was abysmal, the radeon had bad caps.
LZDoom still has the old hacks for AMD GL3 cards AFAIK and the risky modern path option.
I estimate half the performance for an equivalent AMD card on both ports tough.

But hey i've just added low detail mode (160x200) to the list of preset scale modes so all performance problems should now be gone. :mrgreen:
It was very easy but the UI looks horizontally stretched and there's no workaround but it's not that bad and if it works it works(tm). :P
Just kidding 160x100 was already allowed and it was even worse , now i need to add PC Speaker emulation and hey this will be da real thing baby. :P
@dpJudas: too bad it doesn't work on D3D. :wink:

On a hardware renderer that wouldn't make one bit of a difference, unless the card is so weak that it cannot keep up with the driver's performance.
Even with the lousy entry level AMD chip in my brother's laptop I get a comfortable 30 fps on Frozen Time and the GPU in that thing is only slightly better than a Geforce 8600, although it does support Vulkan...

And here's the main reason why my interest in legacy support is so low, if even an entry level card from 12 years ago can handle the game acceptably.

That's awesome. Sadly, AMD's doing a lot of bad things. I thought GZDoom had poor performance due to poor optimization. It turns out AMD's shitty drivers
