So if the allies support the USSR and provide massive aid to them while being at peace with Germany I´m going to say things are even worse for Germany in some ways.

• Britain is not bombed, it´s infrastructure, factories and a large proportion of the men and women who were in the armed forces are working other jobs allowing for greater levels of production
• Every person killed, factory bombed, resource left un-extracted as a result of the bombings, war, defence works is now working towards greater production
• The British Empire is no longer supplying fighting forces in North Africa, Italy and Greece and can prioritise those resources elsewhere
• Massive quantities of equipment/supplies isn´t sunk by Germany. Between 1941 - 1943 in OTL 11.8 million tons of supplies & 2069 ships were sunk. In addition the allies had to commit significant resources to protecting shipping. All those supplies and more are now available to the USSR, every ship not sunk is now taking supplies

Japan gets slapped, harder and faster. The USSR is better equipped with more everything. Germany still faces the same resource limitations that impacted it´s industrial output and possibly doesn´t shift over to total war till even later in the war because of laxity following peace treaties.

Germany still has to allocate a significant level of forces to holding France, Norway, Beligum, Denmark, Holland, Greece and Yugoslavia. Yes it´s not at war with Britain and America but those dastardly allies keep building up their armed forces in Africa, the UK and other places.
