GPU questions for p3d2.0

Recommended Posts

Hi everyone,

I'm looking for some advice about a gpu as the title states. I'm looking at the middle of the road processors since I cant afford a 780 or a titan. In particular, i'm looking at the gtx 660 or 760 both with 2gb. Questions are as follows: What benefits would I gain with the 760 over the 660? Also, what type of limitations would I be looking at with only 2gb of ddr5? I realize its kinda early in the game since p3d2.0 just released, but any advice would greatly appreciate it

I upgraded my 660 to a 760 recently. The 760 runs nicely for me with reasonable slider settings (higher than default but not maxed out) on one 1920x1080 monitor and a low resolution second monitor for moving map. However, I've been monitoring the forums here where users are reporting that P3D can use more than 2 GB VRAM--possibly even with one monitor, which would be astounding and a feat never performed by any game to my knowledge (games like Battlezone maxed out are well below 2GB memory at 1080p). I plan to do some testing of that when I'm back home on Sunday and will report back. My guess is that the performance of the GPU will be a limiting factor before the 2GB level is reached, so that you would need to keep sliders reasonable anyway, which would keep you below 2GB usage. If so, then the 760 is an ideal price/performance choice for a single monitor setup. I would definitely purchase it rather than the 660 since the price is not much more.

760 vs 660, the 760 is a little bit better all the way around. Now 760 vs 660ti,  that's a close one.

At 2gb you will be fine, as long as you don't crank up the settings. With very high settings (not maxed), I normally see 1.5gb to 1.8gb usage. Maxed at JFK I was seeing 2.6gb at 1920/1080. It hit 3gb just for a second, but was normally around 2.6gb or slightly below.

Ntme9, was that with a single monitor?

Only with all sliders maxed out or have you ever gotten over 2GB with, say, medium LOD and some shadows off?

JFK, heavy weather Rain/Snow, CS737, NO AI. Setting all on medium, shadows off, was using around 2.5 and a little higher.

Its going to be very very rare to hit 2gb at those settings, if not ever.

Wow, really? I guess I need to do more testing with weather.

Very interesting guys.  Thanks for your responses.  Not sure about what resoultion I'll be running the sim at.  I'm using a single samsung 42 inch plasma as my tv/computer set up.  I guess what my expectations are, if I am to switch to prepar3d and buy a new graphics card, is something between $200-$300 dollars that will not allow me to max everything out, but get me superior graphics and smoothness over what FSX is providing me now.  I'm not looking to max everything out.  Another factor though is I like complex addons such as the PMDG 737 (once its released for prepar3d) and fly tampa sceneries. I would imagine I would hit that 2gb vram wall pretty easily in these addons. As far as the 4 GB GTX 760 goes, I found one for $300 on amazon.  Crazy to me that P3Dv2 needs that much vram.  Looking forward to what you have to say about your test this weekend Mark.  Thanks again to all for the help and advice

Check newegg. They had some 760s on sale today + you get a software bundle.

will do.  Thanks Bonchie


Another option I guess would be to look for a card with 3GB DDR5 but those seem harder to find

Well just opened my computer case and discovered I only have a 500w PSU.  That is going to cross the 760 off of the list I think even though my i7 3770 isnt overclocked.

You can get an 800-1000 watt power supply on sale today for probably no more then $25.

 

Don't let that stop you.

I may add that was two monitors with an FMC undocked on the second monitor.

The problem is that now having to buy a PSU is going to throw my budget off.  I cant seem to find a psu for under $25, even on black friday.  I dont want to buy a piece of junk that is going to fry my pc either.  Think I'll probably stick to FSX and my current set up and hope for prices to come down on GPUs in the not so distant future

You can likely get by on 500 watts. Take a look at some of the reviews for the 760. Total system load is in the 300-400 watt range.

Thanks Mark but not on this psu.  It's a piece of junk!  Doesnt have sufficient 12v amps.  Im suprised my pc turns on as is.  Another factor is that I live in Ecuador so quality pc components are hard to come by.  Gonna keep my eyes on black friday deals, but if i dont find anything now its ok.  FSX is still working well enough for me where i dont have to rush into p3d until me and my bank account are 'Prepar3d.'  Thanks again for all the advice

Hello boys buy me Prepar3D Tuesday v2, I have a PC, well judgad yourselves not want to sound arrogant:

 

my pc

 

PROCESSOR: Intel i7 4770k Haswell

 

Motherboard: ASUS z87pro

 

Memory: Kingston HyperX (red) 16 Gb

 

2 SSD 250 Gb each in RAID0 = 500 GB

 

1disco duro seagate de 3Tb

 

Graphics Card: ASUS GTX 780

 

Power supply 1000 watts

 

Liquid-cooled 120 Xl COOLER MASTER Seidon

 

aluminum case with three fans.

 

sorry for disturbing, I Prepar3D with REX and license to prepar 3D Y Orbx FTX GLOBAL in Prepar3D and fps is not going very well, not the settings I have all the maximum texture 1024. and I also wanted to ask, with lso FSX PMDG and Captain Sim to complete the migration? since in theory Prepar3D unlocks the power of the machine does not? and other questions have to play nvidia inspector or needless?

 

 

Thank you very much in advance.

I got the EVGA GTX760 for $250. It comes with 2GB DDR5 and I'm very happy with it. Just below max on all the scenery settings and I'm between 25-35 FPS with scattered clouds in Los Angeles and right at 20fps in the middle of a snowstorm at Anchorage Alaska and still smooth. running 1 monitor currently at 1920x1020.

 

I got the EVGA due to it's high ratings on review sites. It also came with 2 free games via my Amazon purchase although it wasn't advertised as doing so (they sent a separate email after purchase with instructions to redeem). Assassin's Creek Black Flag and Splinter Cell. -- Not a bad deal all in all.

 

Also I plan on buying a second one and setting up SLI once Prepar3d supports this hopefully in v2.1
