VRAM - AMD/Nvidia, why does it differ?

[humbug]

Dice didn't make the game - can't remember who did but a lot of it was handed off to some smaller studio who seem to have uh cut some corners.

Ah, ok.

The thing is it's not just pc guys that are unhappy as a lot of the complainers are also console players. Every racing game should have wheel support which to me is just common sense.

No wheel support on Console?

I hear my Brother in law ranting already....

@LtMatt

What game is this you are using

Does it have an in game benchmark

Does it scale on four cards.

Need For Speed Rivals. No in game benchmark. Crossfire support is good for two cards, good scaling. No SLI support AFAIK, this could change via a driver though. However 3/4 cards would be pointless. Even with two cards max usage i see is 75%. Don't believe the game engine can benefit from more cards because of limitations ive mentioned previously.

I'm assuming Dice is involved at some level as the NFS games are using the FB3 engine now but most of the development was done by Ghost Games - given its based on that engine I have no idea how they ended up with an update rate tied to the fps as the engine handles all that asynchronously out the box fine. (Or for that matter the lack of input support as again its something the engine does natively).

Yeah have to admit i didn't know about the fps lock either before i bought it. I got it via the MM for £19 though so not too bad. That said though it doesn't take too long to get used to 30 fps imo. You can increase it as well. I recommend 40fps as a good compromise, smoother but you can't have resolution scale as high.

I recommend anyone who can't get on with 30fps t try these settings. Highest in game settings, disable motion blur. Quit.

Right click game in origin, properties. Cut and paste this in the shortcut.

-GameTime.MaxSimFps 40 -GameTime.ForceSimRate 40+

Click apply. Create a User.cfg file (same as BF3/4) and add the res scale like this

Render.ResolutionScale 1.7

1.1-2.0 works. 2.0 = 200%

Save the file as ALL FILES, not a txt file.

Remember if the game drops below the fps limit you set above it goes in slow motion. Its unplayable so it might take some tweaking till you get it right. If you want 60fps might be best leaving res scale at default and not changing it.



No idea its the only pad i have so have not tried other options.

My understanding is that the gameplay speed is actually locked to the fps (hence why lower fps results in slow motion). So if you increase the FPS you also speed the game up. There are videos on YouTube of it. I think 60fps makes the game run twice as fast as 30 fps. I'd imagine 40 fps is making the game run 33% faster (I don't mean just framerate but actual car speeds).

Not actually sure if it affects the AI car speeds though, might just be yours. So you could be giving yourself a 33% speed increase!

Sounds about right. I did try it and it didn't seem to give either of us an advantage. I'm happy with 30fps at 1440P +170% resolution scaling tbh.

Tried this scaling thing at 150% on BF4, Ultra preset and vram usage was at 1995mb and performance was jerky.

So set it to high settings preset and 150% scaling and vram was 1580mb and performance was as jerky as ultra.

So my 670 has no gpu grunt to run at 150% scaling, dont know what that res would work out at anyway.

The game gave me a pretty bad headache, going round fast corners were the worst. Uninstalled now :l

Im intrested in rivals .. is it much different from the other NFS games?

One thing that has not been mentioned is the quality of the VRAM chips used. On a 6gb Titan you can pull some huge memory overclocks, on a 4gb 290X you would be lucky to reach the Titan's stock memory clock and that's using a smaller amount of memory. There is a cost to quality as well.

I'm glad someone mentioned the quality aspect.

Both are obviously good with marketing but I've sometimes felt Nvidia give what most people need and AMD try to outdo the spec's even if it won't make much difference to most people in reality.
ie, what's the point in complaining about an Nvidia product only having 2gb of ram when you game at say 1080. By the time the memory is an issue at that res the card wont be powerful enough anyway. In some benchmarks I noticed recently the 690 (2GB) is still competitive against the AMD 512bit 4GB cards even at 1440p if I remember correctly.
