[Survey] How many of you CANNOT run GZDoom's OpenGL renderer

[Blzut3]

What are we running that's a problem for ATI cards? I just tried a few wads myself and got anywhere between 170-500fps on my HD5770. Of course even if it runs smoothly I wouldn't run the OpenGL renderer anyways.

Edit: Ahh found one area where the ATI drivers suck (I assume anyways). Turned on the automap and that 500fps went down to 90.

Try some heavily detailed map for a change. On anything 'normal' the problems won't show. ATI was generally far behind NVidia as soon as CPU performance became the bottleneck. The graphics hardware is definitely fast enough but the driver can't prepare the data fast enough.

You are using Linux, aren't you? Maybe it's a Windows problem...

I ran through kdizd and only saw about 3 areas where the frame rate dropped below my vsync of 75hz. Afterwords I tried a few of the benchmark maps using warp to get to the locations specified in the result text files (since the save games and what not have apparently been removed) and I did see some significant drops there.

Highly doubt it makes a significant difference. Supposedly everyone hates the Catalyst drivers for Linux, but I honestly haven't had a problem with them.

What's your system specs.

The thing is, some rather recent ATIs merely get the same performance out of GZDoom than my 4.5 year old system with a Geforce 8600 and from today's standards underpowered early generation CoreQuad processor. Meaning, performance with these systems is not bad, but it also isn't good. Considering the hardware specs it's disappointing though that a Geforce that's 2 generations behind can so easily compete with modern ATIs.

I'm running Kubuntu 11.10 64-bit on:
Intel Core-i5 760 (Quad Core 2.8GHz)
2x4GB Dual Channel DDR3 1333MHz
XFX ATI Radeon HD5770 (Single slot card, this is the primary reason I use ATI hardware)
Gigabyte GA-P55A-UD3

On a somewhat related note, apparently Catalyst's OpenGL support only runs well with OpenGL 1. With KDE threatening to drop support for catalyst you might have some hope of AMD's driver improving. (Assuming they care at all about their Linux users.) I'm almost tempted to run some benchmarks on how well GZDoom runs on the open source drivers (probably horribly since they're not really that great for gaming yet), but I don't want to screw up my graphics setup if I don't have to.

Haven't experienced any issues with GZDoom on my i7 and GTX 560

Looks like I'm the only one here that cant completely use GZDooms OpenGl shaders and brightmaps. I use a windows 7 laptop with an Intel HD graphics card and I have all the options for the shaders turned on and nothing happens. The OpenGl shaders and brightmaps works perfectly with Zandorum but does not work at all with GZDoom. Looks like some one wants me to shell out the extra bucks for a new laptop fully compatable with GZDoom or to buy a new graphics card. That's ok I'm sticking with Zandorum for this reason.

Have fun then using an outdated version of GZDoom.

I'm on 2 GTX460's and can run GZDoom hardware renderer with no issues, although certain parts of Winter's Fury and MAP02 of NDCP2 do cause a noticeable frame drop.

That's the perfect recipe for not being able to run modern engines.


Amd since this thread got resurrected I might as well hijack it for one question:

When starting GZDoom, does anyone still get a GL version below 2.0 reported?
Keeping to keep these ancient graphics hardware operational is by far the biggest obstacle I'm facing. There's an unbelievable amount of old cruft in the engine just to be able to run on pre 2.0 hardware and this alone is completely stalling any chance of improvement.

[Enjay]

GL_VERSION: 3.3.0 for me.

[Nash]

My GL_Version says 4.4.0 (nvidia GTX 460)

[Blue Shadow]

3.3.12422 for me.

[E.C.S]

GL_VERSION: 4.4.0. Using a Nvidia GeForce GTX 650 Ti.

[The Zombie Killer]

It's probably a completely stupid suggestion, and I deserve a punch in the face for even thinking of it, but if there are enough people with GL versions older than 2, then why not have the old GL renderer available as an option just like the software renderer is? Then you could have an updated version that would improve upon things.

Of course, I would imagine this would be an absolute hell to maintain and keep organised. I don't expect it to actually happen.

EDIT: I have GL version 3.3.12618
My older laptop is getting repaired from a HDD failure at the moment, but I'm pretty sure it's in the 3 range as well.
