Civic with FPS terrible drops in any track offiline/online

Hi, I would appreciate your help on this issue, I have also refrred on other thread.

When jumping into the Civic i get massive frame drops, circuit does not matter, i did extensive testing and my conclusions:

With any other ISI car in a ISI track (Clio) I get always above 100FPS with almost full settings with 20 AI (offline)If I jump to the Civic keeping the same settings I get good frames on the pit (same as the Clio) but terrible FPS drops on the grid with 20 AI offline, about 20 to 30 FOPS, which makes the sim terrible, to get at least 60FPS i need to change setting to full minimum...... very unpleasant....

ISI could you please look to this

I have a fairly good gaming set, FX6300 (4.4+7970+8RAM)

 

The Clio has less detail by far than the Civic. The same settings are not going to give you the same performance. 20 AI is MASSES of detail. It's quite obvious what you need to do, as already advised. There's nothing to be looked into. It;s a more detailed car, which requires more from your machine, so you have to adapt to that.

 

Hi many thanks for your reply.
Do not want to insist on this, however none of the other ISIs car need so much resources, even lowering the AI details to low (which should also reduce the need for such high resources substantialy.....) not enough boost, just about 10FPS.
I just leave the honda to the side for now.

 

Lol. Yeah it's quite obvious what you need to do (Swap your AMD card for a Nvidia card?). 7970 should not be able to handle 20 opponent cars without everything set to minimum, nothing strange with that...

 

Lol you are saying that a 7970 O.C can not handle a PC game? All other sims run on the same machine really with very high settings, also RF2, with the Honda excluded.
Pit 220 fps grid 20? Lol

 

Civic is the latest car therefore is fair to say it's got the most details of any ISI car, so you will have to lower settings just as everyone did when Silverstone was released.
Having said that I can run 24 AI at lock Drummond with medium settings with my rig, overcooked HD7850.

I suggest a full reinstall of rf2 to see if that helps, latest build has shadow problems which could also be affecting performance. (if you have these problems of course).


edit: don't compare to other sims, every sim/game is different in many aspects and rf2 has by far the most cpu usage of any sim due to many factors of the game.

 

The difference between the Civic and the rest of the ISI cars is amount of textures.
The C6R for example has a skin.dds 5.33MB in size and that's it.

The Civic's Nr. 1,2,55,77 have a
skin.dds 5.33 MB
driver.dds 2.7MB
extra.dds 1.3 MB
helmet.dds 0.7 MB
windowsout.dds 0.7 MB
windshieldin.dds 5.33 MB
windshieldout.dds 1.3 MB

total = 17.36 MB unique textures for a single car

With a 2GB 670GTX I can run 21-23 (depends on the skins loaded) AI cars at max settings at Silverstone. With 24 cars I get an instant crash to desktop while loading the track because my gfx card runs out of memory. The same happens online. Everything is ok until you reach the limit of your vram. There shouldn't be an instant crash because in practice you see an temp car until you go back to pits.
If I race on a track that needs less resources (Mid Ohio for example) there are no problems at all.

 

in the VEH for the Civis there is also this line:
Sponsor="civic_btcc_1EXTRA7.dds" SponsorTexStage=3
is that the extra.dds you're referring too?

Might be worth trying to run a race without Cars #1, 2, 55 & 77 just to see if there's a vast FPS improvement {makes mental note!}

 

Thanks for your constructive posts.
Must be something diferent from any other car.... Something that increases LOaDs of mem usage ...

 

Yep the extra.dds contains some high res sponsor textures.

I don't believe you see an improvement in fps by leave out the yuasa and pirtek cars. When everything fit into your vram the performance is good, if not, you see a ctd. There is something in between and that has to do with mystical "system gpu memory". Mystical because there almost no useful information about this. Looks like modern gfx cards can make use of the system memory in some cases, which is much slower than vram and this may lead to strange performance drops sometimes. In my case (23-24 AI cars at Silverstone, alt-tab out, alt-tab in) the fps go from 60 down to 3 for some seconds (you can see the red texture loading bar in the fps counter goes wild) and back to normal. Not sure why this happens but it looks like a bug with the nvidia drivers.

 

so i decided to look at the forums after i concluded it was the Honda killing my FPS, so are we saying this is the way it is? take Lime for an example, with Honda i lose up 20fps compared to any other car!

can we then assume that future cars are going to be more of a FPS killer? 30fps on the next car and 40 on the next? and each different car i decide to drive in i have to change graphic settings first?

 

My theory about the CTD's experienced with Honda + Silverstone is that it's a result of hitting the memory cap of a 32-bit application. When loading Silverstone with 25 AI Civics, rF2 uses roughly 3.1-3.2 GB of system RAM moments before CTD, which is well under the 4 GB theoretical limit. But I stumbled across this thread, which states that a directx9 process has to maintain a copy of its used GPU memory in the main memory. This is still somewhat speculation as I'm not familiar with directx9 from a programmers point, but I can consistently reproduce the CTD always at around 3.2 GB of application memory usage, also on other large tracks such as the modded Nordschleife. This makes me believe that we are actually hitting the 4 GB limit and that the remaining ~0.8 GB is reserved for a copy of GPU memory or other resources.

Well, this is just a theory so far, but to me it makes more sense than that the crash would occur due to filled VRAM. The game should still run even after running out of VRAM, although not very smoothly.

 

His expectation is for the Civic to have Clio FPS. That isn't realistic regardless of video card manufacturer, as I explained in my reply.

 

If they are newly created models designed for current machines, yes. Less changes will be required obviously when either older models are updated, or more cars use newer models.

 

I just tested at ISI Silverstone, with 20 AI, me at back of the grid. on my normal in game settings. And at the start of the race, I was getting low 50s FPS, after the grid spread out, mid 60s and higher. I have a 6950 2 GB over clocked moderately , 8 GB DDR2 and AMD Phenom II X4 970. I was pleasantly surprised it was that good, especially at Silverstone.

here are the settings I use.

 

Wrong! My expactaction is to drive the Honda in an acceptable way.
Maybe with my sistem with next car realesed you will say i need to drop resolution.
Instead of optimizimg you are making it worst.
With my sistem i should get good
Frames with one screen, clio, and all other cars.

 

PedroM, there are some, ah, particular characteristics with AMD cards and rF2. Just in case you are unaware the following may help you in general:

-with the 7990 card you can try rolling back to driver 12.11 which offers much better performance for rF2. There is a benchmark in the thread "R9-290 or GTX-770 4GB ??"; by rolling back my driver my minimum fps on this benchmark went from 19fps to 33fps (from driver 13.12) with my 6970. Uninstalling AMD drivers makes me want to sob but I have a list of all the places they hide files if you want a heads-up.

-special effects and shadows are particularly demanding for AMD cards so try lowing these a bit.

I get 50+fps in all conditions apart from a wet starting grid with ~15+ cars where it can plummet down when the spray starts getting up (so a varying fps rate is to be expected). A starting grid is always going to be the most demanding part for the performance.

Number of AI can be quite CPU bound as well, I have recently upgraded to a 4670K from a much slower CPU and I still haven't been brave enough to go over 15 AI at once.

 

I have a 7970 Amd Card very much OC and a 6300@4.4, I understand how demanding this sim can be for a PC, some times i wonder why this is my favourite. I do not want, or need to run with all nice things FULL, on the other way I prefer better simulation.Always run with; no effects Mid shadows, low reflections @1080 -1 screen
What wonders me is the FPS difference when on the Pitt (about 220) and on the grid with 10AI (tested) I get about 35- 185FPs for 10 AI resources..... Why so much?

Whatever...... enough of testing, benchmarking.

Hoppefully doesnt get worst.

 

rolling back is ok if you only play rf2, unfortunately I play other much more recent titles which require latest drivers for various reasons, so it's not an option for me personally.
I'm happy with my overclocked HD7850 (other games are just fine) but now that AC is getting specialist nVidea support I'm starting to think a change maybe in order....except I can't afford it

 

I don't have CTD.

I do a test race with 21 cars no problems



i use low resolution 1600x900 to get better fps with my HD5850
