BAD GPU emulador/simulator?

category: offtopic [glöplog]
How can I slowdown my GPU, or simulate a worse card?

using a virtual machine like virtualbox with appropriate settings?
depends what you mean by "worse card" is it only the clock or some features missing ?

I want an emulator for a GPU that is faster than mine that runs at fullspeed.
Just the clock is fine I guess. I'll just belive that OpenGL <2.0 will behave correctly (yeah I'm forced to use it).

I'm sure you do ;)

can use ATITool or something like that to downclock it.

I guess you can tweak your engine to have a "slowmode" setting where you force resolution to be 4096x3072 with 16x supersamping, all your textures to 8kx8k, and all VBOs to be disabled... I agree it would be nicer to do it in the control panel, tho.

Though iq, it certainly is not all that predictable and concrete as a well-defined limitation now, is it?

However I am curious, xernobyl; what's the relation between low clock frequencies and software behavior? It's not like because of the clock mutexes will cease locking or opcodes will rearrange themselves differently.

Assuming that you're not on a laptop.. how about buying an out-of-date card off eBay for 99p?

Yes, just creating a rendertarget (+ Z-Buffer) with a higher-than-the-display resolution would help, as would downclocking the GPU. Combining both should get you relatively far.

decipher: some effects can be framerate dependent, like feedback. Slower card = totally different visuals in some cases.

AtiTrayTools has an option (under advanced setting) to force the maximum pixel/vertex shader version supported by the hardware. Dunno if there is an option for OpenGL version (it has been years since I last used it).

glFlush() all the time, followed by sleeps.

I agree with evilpaul. You could just buy an old card. This has also the advantage that you could test on Nvidia and ATI. I'm not sure if it is a problem to have the ATI and the Nvidia driver installed at the same time, never tried it...

something to keep in mind is that, especially with iq's suggestion or just generic downclocking of processors/memory, older or "worse" hardware potentially runs on different circuitry/logic alltogether a.k.a it's not a linear factor at play

i find running/devving on x3100 (my always on hand laptop has it) to be quite good a test for slowpoke tiled shit hardware versus running the results on a decent box at home every now and then

(anyone else here noticing that as soon as you've got a) a job (or time-consuming equivalency ;-)) and b) a solid dev. env running on a laptop you stop working on your home dev. box?)

...and then, c) when you have a decent enough dev/test box at work, you get rid of your home dev box

You could ask someone with the hardware to test it for you.

i bought a new desktop during my recent redundancy, beefy gpu.. but in the 3 months ive had it its only been used for irc, web surfing and not much coding at all ;) Considering that with my new job I get a solid 2 hrs coding time on the train, I usually get home and just plug in the laptop again and code on that after a day at the office if I need to code ;)

anyways....... soz off topics.

ooooooh maaaan! so your the one that trains off the code!!

I do database stuff at work, with C# and Linq... yipee!

i do massages and hand-jobs at work. and you should always have a prev-gen setup for testing stuff. just something small, like a shuttlex (thats what i have...it has xp, a GForce 3, parallel ports, vga ouput and all the ancient stuff)
